Adding Username for Database Connections

Adding Username for Database Connections

For database connections, you can have your users sign in with a username instead of their email address.

Require username

  1. Go to Auth0 Dashboard > Authentication > Database, and select the name of the connection you want to edit.

    Select connection
  2. Locate Requires Username, and use the toggle to enable or disable requiring a username.

    Enable or disable require username setting

To see how this will affect the login screen, select the Try Connection view. Notice that once Requires Username is enabled, new users must enter a username and their email address to sign up.

Login form with username

Users can then login with either their username or their email address. Users who registered while Requires Username was disabled will not have a Username field stored and will have to log in with their email address.

Username length

The default allowed length for usernames is between 1 and 15 characters. However, using the Auth0 Dashboard or via the Management API v2, you can modify the length minimum and maximum (up to a maximum length of 128 characters).
