You can use Google on any device, such as laptops, desktops, smartphones, and tablets. You can also use Google on all operating systems, such as Android, iOS, and others. Therefore, like millions of Android phone users, you can also be using an Android phone and use Google on it. Have you faced Google authentication codes are not working problems? What is it? Well, you know that with a single Google account, you can access all Google services that include Gmail, YouTube, Calendar, Map, Duo, etc. Now, you also know that you can enter for the first time in your Android phone user ID and password to use the same Goole account that you used so far on a laptop or other phone. Now, when you try to sign in to a new device, Google wants you to authenticate that you are really trying to sign in and that no suspicious person is doing so. Therefore, Google sends an authenticator code to your registered mobile number. Using this authentication code, you can access Google on a new device. Now, what happens if the Google authenticator code does not work on Android? How to fix this problem?
Well, Google sends an authenticator code to your registered mobile phone number via SMS, through which you can access Google on a new device. If you are facing this problem with your Google Authenticator code while using an Android phone, it may occur due to the reason why in your Google Authenticator application the time is not synchronized correctly. This should solve the problem that Google authenticator codes do not work.
Now that the following screen appears, the application will confirm that your phone's time has been synchronized and you can now use your verification codes to sign in to your Google account. You can see that when you have synchronized time, it will only affect the internal time of your Google Authenticator application available on your Android phone. This will not change the time in the date and time settings of your Android phone.
Now, the problem of Google authentication codes does not work on Android must be solved and, otherwise, you can seek help.
