How to fix ‘Authentication is Required” Google Play Account Error in Android Mobile
You must have seen specially when you are trying to download and install an app from the Google Play Store you get this account error message, “Authentication is Required”. Also this error keeps popping up in your notification and you keep on cancelling it. So here are the few methods you can try to fix this issue and have a relief.
Remove your Google account
As this error may simply be a sign-in issue, which sometimes occurs when the Play Store is updated you can remove your Google account. Simply go to phone’s main Settings menu and then Accounts and simply remove the Google account you have registered. Once you’ve done this, you can re-add the account and it should work just fine. Also clear your data from the Google Play Store before doing this.
Be sure that you know the account password so you can add it again. Now, don’t re-add your Google Account from the actual Account menu in Settings, but open the rogue Google Play Store app on your phone or tablet, and when prompted for your user name and password, enter those inside the Play Store itself.
Clear data from the Google Play Store
As per Google’s own advice on the matter, you need to go into your phones Settings then to Apps or Application Manager list, scroll to find the Google Play Store app, and clear the Play Store’s data with the respective button.
Uninstall Play Store updates
Sometimes the problem is not with your credentials but the Play Store itself. Go to the Play Store in Settings tap Applications and hit Uninstall updates. This will take you back to the original version of the Play Store that was installed on your device. Then, all you need to do to fix the error is install the latest version of the Google Play Store and sign in once again.
Now these methods must have fixed the Authentication required error and your app downloading and installation should be working now, and a new account will be added in your list in the Settings menu, though you may still need to allow it individually the first time you enter apps and sites where your Google credentials are needed.
