What's happening
Codes can stop working for a few reasons: a new or reset phone that no longer has the authenticator, an app that lost its accounts, or a phone clock that's drifted so time-based codes don't match. The fix depends on which it is.
What to do
First, check your phone's date and time are set automatically — that fixes many code failures. If you can't produce a working code, use a saved recovery code to sign in and re-enrol. With no codes, follow account recovery for identity-verified access. See also moving your authenticator.
