If you are having trouble using the ID.me Authenticator app as a Code Generator for multi-factor authentication (MFA), first be sure that you are entering the code before the timer reaches zero. (Each code is valid for 30 seconds, then a new code is generated.)
In the example below, you have 19 seconds to enter the code displayed. If you run out of time, simply wait for a new code to be generated, then enter the new code.
