I am unable to set up 2FA as the codes aren’t being accepted – or – My codes used to work but are now failing.
1. Outdated app – If your Microsoft Authenticator app is obsolete, you might face this issue. You need to update your app from
App Store
or
Google Play Store.
2. Microsoft & Google Authenticator app 2FA codes are based on time and thus require the time on your phone, PC or Mac to be in-sync with the official time.
You can disconnect your device from the internet and as long as its time is still correct, it will successfully generate correct 2FA codes. However, manual time settings and offline devices eventually slip out of sync.
If your device time is out of sync or if you have changed time zones, the best way to fix it is to change the time settings on your device from “Manual” to “Automatic”. If it is already set to ‘Automatic’ toggle it off and back on and the restart the device to re-sync the app.
How to update the time on your device:
Android Samsung
Android Pixel, Huawei etc.
Android Nokia
iOS iPhone or iPad
Windows
Mac
Some devices settings may vary, if your device is not listed or the instructions do not match, please search online for your phone model and “update time and date”
3. Google Authenticator on some devices has it’s own internal clock. To set the correct time:
On your Android device, go to the main menu of the Google Authenticator app.
Tap More and then Settings and then Time correction for codes and then Sync now.
On the next screen, the app confirms the time has been synced. You should be able to sign in. The sync will only affect the internal time of your Google Authenticator app, and will not change your device’s Date & Time settings.
