How To Easily Fix Google Authenticator Code Not Working?

Sync App’s Time

When logging into their accounts on a mobile device, customers may find that their Google Authenticator code needs to be fixed. Surprisingly, the issue can be related to the time settings in Google Authenticator. Well, if your Google Authenticator app is not working on Android or iOS, there might be a problem with the time sync. If the Google Authenticator code is not working, it’s simple to fix. This is how.

Ensure the time on your Google Authenticator app is accurate. Launch the app, select the menu button (the three dots in the top right corner of the screen), and navigate to Settings > Time Correction for Codes > Sync.

After this, you should find that your Google Authenticator code works correctly.

Note: Syncing the time in the Google Authenticator setting does not affect your phone’s time in the Google Authenticator app.

Update Authenticator App

Are you certain that the Authenticator app on your phone has the most recent updates? When was the last time you updated it, and how long has it been? If you are still determining, it may be time for an update. Updates are important to fix existing or new defects in the program, in addition to fixing security flaws. For example, the reason Google Authenticator crashed may have been your app’s age. A simple update will confirm whether this is the case. How can you know whether your Google Authenticator app is up to date?

1 – Open the Google Play Store app on your Android device.

2 – From the top right, click your profile symbol.

3 – Choose Manage apps & devices.

4 – Apps that have recently released updates are marked as “Update available.”

5 – Choose Update.

If a new update for Google Authenticator is available, it will be downloaded within a few seconds. If the Authenticator app truly stopped working due to an update issue, everything should be back to normal. It would be best if you also noted that it is always preferable to have automatic updates activated on your devices. This will prevent any security risks or common bugs from arising.

Install Google Authenticator On Multiple Devices

You may need to be more responsive about depending on one device as an authenticator. You could lose your main device, for example. Its battery may die just when you need it. It might also be unavailable when you travel for any reason. Google Authenticator may have stopped working for a variety of reasons.

In these circumstances, installing Google Authenticator on several devices is an option. You may also use an old phone that you no longer use. You might also install the app on your tablet or laptop in addition to your phone. It is rather simple to set up two devices using Google Authenticator. First, install the app from the Google Play Store on both devices. Then, navigate to the two-factor authentication setting page.

Then you’ll notice a QR code. Use this QR code on your main device first, followed by your secondary device. To see whether it works, enter the numeric code from either device. Both devices will now display identical numeric codes for logging in. You may switch to your backup device if your main device is unavailable. Remember to keep your backup device safe if you do this.

Log In To Google Authenticator Using Backup Codes

You can generate backup codes when you set up your Google Authenticator app in case you lose your original codes and/or they stop working. These codes are numerical strings that can only be used once to log in. Backup codes are quite helpful if you lose your device with Google Authenticator installed. Or if, for any other reason, the Google Authenticator app is not working. Maintaining a duplicate of your backup codes someplace safe is a good idea.
