Login by Auth0

Login by Auth0 provides improved Username/password login, Passwordless login, Social login and Single Sign On for all your sites.

Technical Notes

IMPORTANT: By using this plugin you are delegating the site authentication to Auth0. That means that you won't be using the WordPress database to authenticate users anymore and the default WP login box won't show anymore. However, we can still associate your existing users by merging them by email. This section explains how.

When you install this plugin you have at least one existing user in the database (the admin user). If the site is already being used, you probably have more than just the admin. We want you to keep those users, of course.

Migrating Existing Users

Auth0 allows multiple authentication providers. You can have social providers like Facebook, Twitter, Google+, etc., you can have a database of users/passwords (just like WordPress but hosted in Auth0) or you can use an Enterprise directory like Active Directory, LDAP, Office365, SAML and others. All those authentication providers might give you an email and a flag indicating whether the email was verified or not. We use that email (only if its verified) to associate a previous existing user with the one coming from Auth0.

If the email was not verified and there is an account with that email in WordPress, the user will be presented with a page saying that the email was not verified and a link to "Re-send the verification email".

For both scenarios you may configure in the WP admin whether is mandatory that the user has a verified email or not.

Accesing Profile Information

WordPress defines a function called wp_get_current_user to populate the global variable current_user with the logged in WP_User. Similary we define get_currentauth0userinfo that populates current_user and currentauth0_user with the information of the Normalized profile

Enabling dual (Auth0 and WordPress) login

You can enable the standard WordPress login by turning on the "WordPress login enabled" setting (enabled by default). This will make visible a link on the login page to swap between both.

Using the plugin widget

You can enable the Auth0 as a WordPress widget in order to show it in the sidebar. The widget inherits the plugin settings and it can be overrided with its own settings.

Also, a new layout setting is enabled in order to be shown as a modal. Enabling the "Show as modal" setting, a button which trigger the modal is generated.

Using the login widget as a shortcode

Also, you can use the Auth0 widget as a shortcode in your posts.

The way to use it is just adding the following:


And can be customized by adding the following parameters:

  • form_title: string
  • dict: string, should be a the language or a valid json with the translation (see https://github.com/auth0/lock/wiki/Auth0Lock-customization#dict-stringobject)
  • social_big_buttons: boolean
  • gravatar: boolean
  • username_style: string, "email" or "username"
  • remember_last_login: boolean
  • icon_url: string (valid url)
  • extra_conf: string, valid json
  • show_as_modal: boolean
  • modal_trigger_name: string, button text


[auth0 show_as_modal="true" social_big_buttons="true" modal_trigger_name="Login button: This text is configurable!"]
