If a user has a new device or number, click Reset Two-Factor on the user's detail page. At the next login, the user sets up two-factor authentication again.
How to do it
- Go to Security > Users and click the user.
- Next to the two-factor method (for example SMS), click Reset Two-Factor.
- The dialog explains: "The user will need to set up two-factor authentication again the next time they log in." Click Reset Two-Factor.
Good to know
- If two-factor authentication works by SMS, first check the user's phone number.
- A user without single sign-on can also reset two-factor authentication themselves under Profile > Security. See Changing your profile, language and display.
