How to Activate Flexible Identifiers:

Activating this feature is straightforward and can be done directly within your dashboard. Here’s how:

  1. Navigate to the Auth0 Dashboard > Authentication > Database.
  2. Select the Database Connection you wish to modify.
  3. Go to the Attributes tab.
  4. Click the Activate button within the New Attributes Configuration.
  5. You will be prompted to confirm that you’ve tested these settings in a Development environment. Click Proceed to finalize the activation.

Once activated, the new configuration options will become available, ensuring a seamless transition while retaining your existing settings for email and username configurations.

Bonus - Attributes vs Identifiers

In our system, attributes represent the various pieces of user data that can be stored, such as email, phone number, and username. However, not all attributes serve the same function. While all identifiers must be attributes, the reverse isn’t necessarily true. Only specific attributes can be elevated to the status of identifiers. An identifier is a unique attribute used to distinctly recognize a user within the system. For instance, while email, phone, and username can uniquely identify an individual and hence serve as identifiers, other attributes may simply contribute to the user’s profile without possessing this identification capability. This distinction is crucial for setting up effective and secure authentication processes.
