3. Check whether your Pokemon GO account got banned

One possible reason why Pokemon GO failed to authenticate you is that your account is banned from playing the game. Although the game’s security is too tight now as it uses Google’s SafetyNet API to figure out if the device is rooted or not. However, in the early stages when the game was newly launched, many users were banned from using GPS spoofers, using bots, and other malicious software that ruins a healthy game environment. So, if you have done such things with your account in the past, there are chances that your account has received a ban.

6. Remove Other Devices from Google account

If you play Pokemon GO on multiple devices with the same Google account, the Pokemon GO authentication error will occur for sure.
