Authenticator apps can hold several entries with similar names. Use the entry that was successfully enabled for the Institution account you are signing in to.
Check the work email on the sign-in flow. If you have more than one Institution identity, the authenticator associated with another identity will not verify this one. An old entry created during a cancelled setup can also keep producing codes without matching the enabled factor.
Enter the current six-digit code from the correct entry. If it changes while you are typing, wait for the next code and try again. After a rejected attempt, Institution presents another opportunity to verify; repeated use of the same old code is not useful.
Keep uncertain entries until you have identified the working one and confirmed access. Deleting every entry to tidy the app can remove the only factor that works. If no available entry verifies and you cannot recover the original authenticator, contact support for account recovery. Do not send screenshots of the authenticator list while live codes are visible.
