​
Prerequisites

To enable passkeys as an authentication method for your database connection, you must configure your Auth0 tenant to fulfill the following prerequisites. If these prerequisites are not met and you try to enable passkeys, the Auth0 Dashboard displays the Passkey Authentication Prerequisites readiness checklist and shows any unmet requirements.
After you enable passkeys as an authentication method for a database connection, you can use the readiness checklist to monitor the status of each requirement and access the relevant settings. To view the Passkey Authentication Prerequisites readiness checklist:
  1. In the Auth0 Dashboard, go to Authentication > Database.
  2. Select a connection.
  3. Switch to the Authentication Methods view.
  4. Select Configure on the Passkeys card.

Best practices

To ensure the best experience for end users when using passkeys, consider the items below.
  • Configure a : When a user enrolls a passkey, it associates with the domain. If the domain name changes at any time, all of the passkeys associated with the old domain become invalid. Configure a custom domain for your tenant prior to enabling passkeys to avoid any interruptions for end-users.
  • Enable passkeys for a single database connection: Enable passkeys for a maximum of one database connection.
  • Consider limitations for Organization users: Users cannot use passkeys when creating an account through an Organization invitation email. To allow these users to create passkeys, use an alternate method of user creation or ensure progressive enrollment is enabled.

Enable passkeys as an authentication method

You can enable passkeys as an authentication method for your database connection in the Auth0 Dashboard:
  1. Go to Authentication > Database.
  2. Select a connection.
  3. Switch to the Authentication Methods view.
  4. Enable the toggle on the Passkey card.
Currently, if you enable passkeys for a connection, you must also configure passwords as a backup authentication method. This ensures users can continue to access their accounts from browsers and older devices that may not yet support passkeys.

​
Configure your policy

You can configure the passkey policy for your database connection in the Auth0 Dashboard:
  1. Go to Authentication > Database.
  2. Select a connection.
  3. Switch to the Authentication Methods view.
  4. Select Configure on the Passkey card.
As passkeys already offer a more secure experience, users leveraging passkeys can choose to skip secondary verification challenges, such as CAPTCHA. Users authenticating with passwords or other traditional methods must continue to complete secondary verification when prompted.

Passkey Challenge

This setting determines how users can trigger passkey authentication during login and signup.
Passkey authentication UIDescription
AutofillUsers must log in with their browser’s autofill feature to leverage passkeys. Autofill allows users to select a saved account from a dropdown menu when engaging with the login prompt. With autofill, users do not need to manually enter their credentials.
Passkey buttonUsers must select the Continue with a passkey button on the login prompt.
BothUsers can trigger passkey authentication using autofill or by selecting the Continue with a passkey button on the login prompt.
Users can only use autofill if the functionality has been enabled in their browser settings. If autofill is not available, users can log in using the Passkey button or their traditional credentials.

​
Progressive Enrollment

Enabled by default, progressive enrollment prompts users to create a passkey (if they have not done so already) after logging in with their email and password. This step is not required and users can choose to delay this action every 30 days. Progressive enrollment is useful when migrating users to a new passkey flow as it offers a more seamless transition between authentication methods. When a user creates their passkey, it is added to their account as an authentication method. Their standard email or username and password remain valid and can be used to log in as needed. Passkeys do not replace or invalidate users’ standard credentials.

​
Local Enrollment

Enabled by default, local enrollment prompts existing users to create a local passkey when using a cross-device passkey to log in to a new device. For example, existing passkey users can use a QR code to log in to a new device that is within physical proximity of a previously-enrolled device. If local enrollment is enabled in this scenario, the user is prompted to create a local passkey on the new device after they log in with the QR code. If desired, users can choose to skip this action.
