You can allow users to authenticate to another user’s account by using their own authenticators. For example, if the sharing authenticator option is enabled, the secretary’s account can be linked to the account of boss and the secretary will be able to authenticate to the account of boss by using her own authenticators.
The authenticators that can be linked are: TOTP, HOTP, Password, Fingerprint, Card, and FIDO U2F.
To share the authenticators of a user with another user, perform the following steps:
Login and specify the name of the user to whom you want to link the authenticators to.
Click Linked Authenticators tab on the screen.
Specify the user name whose authenticator you want to use. For example, if you want to use secretary's fingerprint to authenticate to the account of boss, specify the name as Secretary-Fingerprint.
Click Save.
Secretary will now be able to authenticate to the account of boss by authenticating with her own fingerprint.
