Creating a Second Passkey for the Same User on a Different Device Within Auth0

This article explains how to enable end users to add a second passkey on a different device, making it easier to switch between devices.

• Auth0
• Database Connections
• Passkeys

The process below to create a second passkey will only work if the passkey is initially saved on a device other than the device being used for login. For example, if logging into a PC, then the passkey may be saved on a mobile device or YubiKey. If the passkey is saved on the same device, for example, via Microsoft Password Manager on the same device (PC), then there will be no opportunity to add a second passkey.

For the user to be able to create another key on the new device, the following prerequisites must be satisfied:

1. The Local enrollment for passkeys option must be turned on in the Database connection's Passkey configuration
2. The user must log in to the new device with the previous device's passkey. This can be done by selecting the Continue with a passkey button

3. Once the user logs in with the help of the other device, Auth0 will prompt the user with an option to create a new passkey for the current device.

The user can choose to create a new local passkey or continue without creating one. If they choose not to create a new one, they can still log in with the other device's passkey.

See Enable and Configure Passkey Authentication for Database Connections for more information on local enrollment.
