In rare cases, you may receive invalid code errors when attempting to sign in with MFA enabled because the time on your MFA device has drifted. This has been observed with the Google Authenticator app but may affect other MFA methods. If you are using the Google Authenticator app as your MFA device, you can correct this using the following procedures for iOS and Android phones.
- Open the iOS Settings app.
- Select General.
- Select Date & Time.
- Enable Set Automatically if it is not already enabled. Otherwise, disable Set Automatically, wait 10 seconds, and then re-enable it.
- Open the Google Authenticator app main menu.
- Choose Settings.
- Select Time correction for codes.
- Select Sync now.
One you have completed the above procedure for your device type, close and reopen the Google Authenticator app, and attempt to enter the next code again.
