Can Users Register Multiple Verification Methods for MFA?

This article answers the question: can a Salesforce user register and use multiple verification methods for multi-factor authentication (MFA)? Yes, once a user connects a first verification method, they can register additional methods, such as Salesforce Authenticator combined with a third-party authenticator app.

How to Register an Additional Verification Method

To register a second or subsequent verification method, the user must connect it from Advanced User Details within their personal settings after logging in. The detailed registration procedure depends on the verification method chosen by the user.

What Changes When You Register a Second Verification Method

When a user connects (registers) an additional verification method, a verification code is not sent to their email address the way it is for the first verification method. Instead, the user is asked to verify their identity using a verification method that is already connected. For more information, see this article on why a verification code isn't emailed when adding an additional method.

Selecting a Verification Method at Login

After a second or subsequent verification method is connected, the user is prompted to choose which method to use each time they log in. For details on how to select a verification method during login, see this article on selecting a verification method at login.
