UI Options

allowAutocomplete

Determines whether or not the email or username fields will allow autocomplete (<input autocomplete />). Defaults to false.

allowAutocomplete: true

allowPasswordAutocomplete

Determines whether or not the password field will allow autocomplete (<input autocomplete />). Defaults to false.

Set allowPasswordAutocomplete to true for password manager support and to avoid other cases of adverse behavior.

allowPasswordAutocomplete: true

allowShowPassword

This option determines whether or not to add a checkbox to the UI which, when selected, will allow the user to show their password when typing it. The option defaults to false.

allowShowPassword: true

Lock with allowShowPassword set to true and toggled to show the password:

allowedConnections

Array of connections that will be used for the signin|signup|reset actions. Defaults to all enabled connections.

allowedConnections: ['Username-Password-Authentication']

allowedConnections: ['twitter', 'facebook', 'linkedin']

allowedConnections: ['qraftlabs.com']

Examples of allowedConnections:

autoclose

Determines whether or not the Lock will be closed automatically after a successful sign in. Defaults to false. If the Lock is not closable it won’t be closed, even if this option is set to true.

autoclose: true

autofocus

If true, the focus is set to the first field on the widget. Defaults to false when being rendered on a mobile device, or if a container option is provided; defaults to true in all other cases.

autofocus: false

avatar

By default, Gravatar is used to fetch the user avatar and display name, but you can obtain them from anywhere with the avatar option.

var options = {
  avatar: {
    url: function(email, cb) {
      // Obtain the avatar url for the email input by the user, Lock
      // will preload the image before displaying it.
      // Note that in case of an error you call cb with the error in
      // the first arg instead of `null`.
      var url = obtainAvatarUrl(email);
      cb(null, url);
    },
    displayName: function(email, cb) {
      // Obtain the display name for the email input by the user.
      // Note that in case of an error you call cb with the error in
      // the first arg instead of `null`.
      var displayName = obtainDisplayName(email);
      cb(null, displayName);
    }
  }
};

Or, if you want to display no avatar at all, simply pass in null.

avatar: null

Default behavior with Gravatar:

closable

Determines whether or not the Lock can be closed. When a container option is provided its value is always false, otherwise it defaults to true.

closable: false

container

The id of the html element where the widget will be shown.

This makes the widget appear inline within your div instead of in a modal pop-out window.

<div id="hiw-login-container"></div>

<script>
  var options = {
    container: 'hiw-login-container'
  };

  // initialize
  var lock = new Auth0Lock('xxxxxx', '<account>.auth0.com', options);

  // render
  lock.show();
</script>

flashMessage

Shows an error or success flash message when Lock is shown. This object has the following properties:

• type : The message type, supported types are error, info, and success
• text : The text to show.

var options = {
  flashMessage: {
    type: 'success',
    text: 'Welcome!'
  }
};

language

Specifies the language of the widget. Defaults to “en”. See the internationalization directory for a current list of provided languages.

language: 'es'

languageDictionary

Allows customization of every piece of text displayed in the Lock. Defaults to . See English language Language Dictionary Specification for the full list of languageDictionary values able to be altered with this object.

var options = {
  languageDictionary: {
    emailInputPlaceholder: "[e-mail]",
    title: "Log me in"
  },
};

Additionally, check out the Customizing Error Messages page or the Internationalization page for more information about the use of the languageDictionary option.

popupOptions

Allows the customization the location of the popup in the screen. Any position and size feature allowed by window.open is accepted. Defaults to .

Options for the window.open features. This only applies if redirect is set to false.

var options = {
  auth: {
      redirect: false
  },
  popupOptions: { width: 300, height: 400, left: 200, top: 300 }
};

rememberLastLogin

Determines whether or not to show a screen that allows you to quickly log in with the account you used the last time. Requests Single Sign-on (SSO) data and enables a Last time you signed in with message. Defaults to true. This information comes from the user’s Auth0 session, so this ability will last as long as their Auth0 session would (which is configurable).

rememberLastLogin: false

New tenants automatically have Seamless SSO enabled. With this enabled, the rememberLastLogin option will not be relevant because if there is a session in place then the Universal Login page will not be displayed at all. Using Seamless SSO is highly recommended because it provides a seamless authentication experience: users log in once and won’t have to enter credentials again when they navigate either through the applications you have built, or third party apps. If the user is not logged in they will be redirected to the login screen, as expected. Additionally, the Last time you signed in with message will not be available under the following circumstances:

• You used Lock in a Hosted Login Page with the session established using Passwordless authentication.
• You used Lock in an embedded login scenario where responseType: code (indicating the Authorization Code Flow, which is used for Regular Web Apps).

scrollGlobalMessagesIntoView

Determines whether or not a globalMessage should be scrolled into the user’s viewport. Defaults to true.

scrollGlobalMessagesIntoView: false

Theme Options

Theme options are grouped in the theme property of the options object.

var options = {
  theme: {
    labeledSubmitButton: false,
    logo: "https://example.com/assets/logo.png",
    primaryColor: "green",
    authButtons: {
      connectionName: {
        displayName: "...",
        primaryColor: "...",
        foregroundColor: "...",
        icon: "https://.../logo.png"
      }
    }
  }
};

authButtons

Allows the customization of buttons in Lock with custom OAuth2 connections. Each custom connection whose button you desire to customize should be listed by name, each with their own set of parameters. The customizable parameters are listed below:

• displayName : The name to show instead of the connection name when building the button title, such as LOGIN WITH MYCONNECTION for login).
• primaryColor : The button’s background color. Defaults to #eb5424.
• foregroundColor : The button’s text color. Defaults to #FFFFFF.
• icon : The URL of the icon for this connection. For example: http://site.com/logo.png.

var options = {
  theme: {
    authButtons: {
      "testConnection": {
        displayName: "Test Conn",
        primaryColor: "#b7b7b7",
        foregroundColor: "#000000",
        icon: "http://example.com/icon.png"
      },
      "testConnection2": {
        primaryColor: "#000000",
        foregroundColor: "#ffffff",
      }
    }
  }
};

labeledSubmitButton

This option indicates whether or not the submit button should have a label, and defaults to true. When set to false, an icon will be shown instead.

var options = {
  theme: {
    labeledSubmitButton: false
  }
};

If the label is set to true, which is the default, the label’s text can be customized through the languageDictionary option.

logo

The value for logo is a URL for an image that will be placed in the Lock’s header, and defaults to Auth0’s logo. It has a recommended max height of 58px for a better user experience.

var options = {
  theme: {
    logo: 'https://example.com/logo.png'
  }
};

primaryColor

The primaryColor property defines the primary color of the Lock; all colors used in the widget will be calculated from it. This option is useful when providing a custom logo, to ensure all colors go well together with the logo’s color palette. Defaults to #ea5323.

var options = {
  theme: {
    logo: 'https://example.com/logo.png',
    primaryColor: '#31324F'
  }
};

Authentication Options

Authentication options are grouped in the auth property of the options object.

The default scope used by Lock is openid profile email.

var options = {
  auth: {
   params: {
    param1: "value1",
    scope: "openid profile email"
   },
   autoParseHash: true,
   redirect: true,
   redirectUrl: "some url",
   responseMode: "form_post",
   responseType: "token",
   sso: true,
   connectionScopes: {
    connectionName: [ 'scope1', 'scope2' ]
   }
  }
};

audience

The audience option indicates the API which will be consuming the Access Token that is received after authentication.

var options = {
  auth: {
    audience: 'https://{yourDomain}/userinfo',
  }
}

autoParseHash

When autoParseHash is set to true, Lock will parse the window.location.hash string when instantiated. If set to false, you’ll have to manually resume authentication using the resumeAuth method.

var options = {
  auth: {
    autoParseHash: false
  }
};

connectionScopes

This option allows you to set scopes to be sent to the oauth2/social connection for authentication.

var options = {
  auth: {
    connectionScopes: {
      'facebook': ['scope1', 'scope2']
    }
  }
};

A listing of particular scopes for your social connections can be acquired from the provider in question. For example, Facebook for Developers reference has a listing of separate permissions that can be requested for your connection.

params

You can send parameters when starting a login by adding them to the options object. The example below adds a state parameter with a value equal to foo and also adds a scope parameter (which includes the scope, and then the requested attributes).

var options = {
  auth: {
    params: {
      state: 'foo',
      scope: 'openid email user_metadata app_metadata picture'
    }
  }
};

For more details about supported parameters, see Lock Authentication Parameters.

redirect

Defaults to true. When set to true, redirect mode will be used. If set to false, popup mode is chosen.

var options = {
  auth: {
    redirect: false
  }
};

redirectUrl

The URL Auth0 will redirect back to after authentication. Defaults to the empty string "" (no redirect URL).

var options = {
  auth: {
    redirectUrl: 'http://testurl.com'
  }
};

When the redirectUrl is provided (set to non blank value) the responseType option will be defaulted to code if not manually set.

responseMode

Should be set to "form_post" if you want the code or the token to be transmitted via an HTTP POST request to the redirectUrl, instead of being included in its query or fragment parts.

Otherwise, this option should be omitted, and is omitted by default.

var options = {
  auth: {
    responseMode: 'form_post'
  }
};

responseType

The value of responseType should be set to “token” for Single-Page Applications, and “code” otherwise. Defaults to “code” when redirectUrl is provided, and to “token” otherwise.

var options = {
  auth: {
    responseType: 'token'
  }
};

When the responseType is set to code, Lock will never show the Last time you logged in with message, and will always prompt the user for credentials.

sso

Defaults to true. When set to true, enables Single Sign-On in Lock.

var options = {
  auth: {
    sso: false
  }
};

Database Options

additionalSignUpFields

Extra input fields can be added to the sign up screen with the additionalSignUpFields option. Each option added in this manner will then be added to that user’s user_metadata. To learn more, read Understand How Metadata Works in User Profiles. Every input must have a name and a placeholder, and an icon URL can also be provided. Also, the initial value can be provided with the prefill option, which can be a string with the value or a function that obtains it. Other options depend on the type of the field, which is defined via the type option and defaults to “text”.

Option additionalSignUpFields Intended for use with database signup only

The additionalSignUpFields are intended for use with database signups only. If you have social sign ups too, you can ask for the additional information after the users sign up (see this page about custom signup for more details). You can use the databaseAlternativeSignupInstructions i18n key to display these instructions.

The new fields are rendered below the regular sign up input fields in the order they are provided.

Text Fields

Text fields are the default type of additional signup field. Note that a validator function can also be provided.

var options = {
  additionalSignUpFields: [{
    name: "address",
    placeholder: "enter your address",
    // The following properties are optional
    icon: "https://example.com/assests/address_icon.png",
    prefill: "street 123",
    validator: function(address) {
      return {
         valid: address.length >= 10,
         hint: "Must have 10 or more chars" // optional
      };
    }
  },
  {
    name: "full_name",
    placeholder: "Enter your full name"
  }]
}

If you don’t specify a validator the text field will be required. If you want to make the text field optional, use a validator that always returns true like this:

var options = {
  additionalSignUpFields: [{
    name: "favorite_color",
    placeholder: "Enter your favorite color (optional)",
    validator: function() { 
      return true;
    }
  }]
}

If you want to save the value of the attribute in the root of your profile, use storage: 'root'. Only a subset of values can be stored this way. The list of attributes that can be added to your root profile is here. By default, every additional sign up field is stored inside the user_metadata object.

var options = {
  additionalSignUpFields: [{
    name: "name",
    storage: "root"
  }]
};

Select Field

The signup field type: "select" will allow you to use select elements for the user to choose a value from.

var options = {
  additionalSignUpFields: [{
    type: "select",
    name: "location",
    placeholder: "choose your location",
    options: [
      {value: "us", label: "United States"},
      {value: "fr", label: "France"},
      {value: "ar", label: "Argentina"}
    ],
    // The following properties are optional
    icon: "https://example.com/assests/location_icon.png",
    prefill: "us"
  }]
}

The options array items for select fields must adhere to the following format: {label: “non empty string”, value: “non empty string”}, and at least one option must be defined.

The options and prefill values can be provided through a function:

var options = {
  additionalSignUpFields: [{
    type: "select",
    name: "location",
    placeholder: "choose your location",
    options: function(cb) {
      // obtain options, in case of error you call cb with the error in the
      // first arg instead of null
      cb(null, options);
    },
    icon: "https://example.com/assests/location_icon.png",
    prefill: function(cb) {
      // obtain prefill, in case of error you call cb with the error in the
      // first arg instead of null
      cb(null, prefill);
    }
  }]
}

Checkbox Field

The third type of custom signup field is the type: "checkbox". The prefill value can determine the default state of the checkbox (true or false), and it is required.

var options = {
  additionalSignUpFields: [{
    type: "checkbox",
    name: "newsletter",
    prefill: "true",
    placeholder: "I hereby agree that I want to receive marketing emails from your company"
  }]
}

Hidden field

The signup field type: "hidden" will allow you to use a hidden input with a fixed value.

var options = {
  additionalSignUpFields: [{
    type: "hidden",
    name: "signup_code",
    value: "abc123"
  }]
}

Some use cases may be able to use additionalSignUpFields data for email templates, such as an option for language preferences, the value of which could then be used to set the language of templated email communications.

allowLogin

When set to false the widget won’t display the login screen. This is useful if you want to use the widget just for signups (the login and signup tabs in the signup screen will be hidden) or to reset passwords (the back button in the forgot password screen will be hidden). In such cases you may also need to specify the initialScreen, allowForgotPassword and allowSignUp options. It defaults to true.

allowLogin: false

allowForgotPassword

When set to false, allowForgotPassword hides the “Don’t remember your password?” link in the Login screen, making the Forgot Password screen unreachable. Defaults to true. If you are using a database connection with a custom database which doesn’t have a change password script the Forgot Password screen won’t be available.

allowForgotPassword: false

allowSignUp

When set to false, hides the login and sign up tabs in the login screen, making the sign up screen unreachable. Defaults to true. Keep in mind that if the database connection has sign ups disabled or you are using a custom database which doesn’t have a create script, then the sign up screen won’t be available.

Also bear in mind that this option only controls client-side appearance, and does not completely stop new sign ups from determined anonymous visitors. If you are looking to fully prevent new users from signing up, you must use the Disable Sign Ups option in the dashboard, in the connection settings.

allowSignUp: false

defaultDatabaseConnection

Specifies the database connection that will be used when there is more than one available.

defaultDatabaseConnection: 'test-database'

initialScreen

The name of the screen that will be shown when the widget is opened. Valid values are login, signUp, and forgotPassword. If this option is left unspecified, the widget will default to the first screen that is available from that list.

initialScreen: 'forgotPassword'

loginAfterSignUp

Determines whether or not the user will be automatically signed in after a successful sign up. Defaults to true.

loginAfterSignUp: false

forgotPasswordLink

Set the URL for a page that allows the user to reset their password. When set to a non-empty string, the user will be sent to the provided URL when clicking the “Don’t remember your password?” link in the login screen.

forgotPasswordLink: 'https://yoursite.com/reset-password'

showTerms

When set to true displays the languageDictionary.signUpTerms string. Defaults to true.

showTerms: false

mustAcceptTerms

When set to true displays a checkbox input alongside the terms and conditions that must be checked before signing up. The terms and conditions can be specified via the languageDictionary option. This option will only take effect for users signing up with database connections. Defaults to false.

mustAcceptTerms: true

prefill

Allows to set the initial value for the email and/or username inputs. When omitted, no initial value will be provided.

var options = {
  prefill: {
    email: "[e-mail]",
    username: "someone",
    phoneNumber: "[phone]"
  }
};

signUpLink

Set the URL to be requested when clicking on the Signup button. When set to a non empty string, this option forces allowSignUp to true.

signUpLink: 'https://yoursite.com/signup'

usernameStyle

Determines what will be used to identify the user for a Database connection that has the requires_username flag set (if it is not set, usernameStyle option will be ignored). Possible values are "username" and "email". By default both username and email are allowed; setting this option will limit logins to use one or the other.

usernameStyle: 'username'

Enterprise Options

defaultEnterpriseConnection

Specifies the enterprise connection which allows to login using a username and a password that will be used when there is more than one available or there is a database connection. If a defaultDatabaseConnection is provided the database connection will be used and this option will be ignored.

defaultEnterpriseConnection: 'test-database'

defaultADUsernameFromEmailPrefix

Resolve the AD placeholder username from the email’s prefix. Defaults to true.

defaultADUsernameFromEmailPrefix: false

Passwordless Options

passwordlessMethod

When using Auth0LockPasswordless with an email connection, you can use this option to pick between sending a code or a magic link to authenticate the user. Available values for email connections are code and link. Defaults to code. SMS passwordless connections will always use code.

passwordlessMethod: code

Other Options

configurationBaseUrl

Overrides the application settings base URL. By default, it uses the provided domain. This option is only necessary if your specific use case dictates that your application does not use the default behavior.

configurationBaseUrl: "https://www.example.com"

languageBaseUrl

Overrides the language source url for Auth0’s provided translations. By default, this option uses Auth0’s CDN URL https://cdn.auth0.com since this is where all of the provided translations are stored. By providing another value, you can use another source for the language translations if needed.

languageBaseUrl: "https://www.example.com"

hashCleanup

When the hashCleanup option is enabled, it will remove the hash part of the callback URL after the user authentication. It defaults to true.

hashCleanup: false

connectionResolver

When in use, provides an extensibility point to make it possible to choose which connection to use based on the username information.

Has username, context, and callback as parameters. The callback expects an object like: {type: 'database', name: 'connection name'}. This only works for database connections. Keep in mind that this resolver will run in the form’s onSubmit event, so keep it simple and fast.

This is a beta feature. If you find a bug, please open a GitHub issue.

leeway

The leeway option can be set to an integer - a value in seconds - which can be used to account for clock skew in ID Token expirations. Typically the value is no more than a minute or two at maximum.

leeway: 30
