What Are the Possible Reasons For the “Pokemon Go Unable to Authenticate” Error?

Here are some of the reasons why Pokemon Go might trigger the authentication error:

Wrong Username or Password: There is a high possibility that you might forget the sign-in process sometimes. You might face an authentication error if you have registered the account with Facebook or Gmail but trying to log in through your email directly.

Using WiFi and Tethering Account: When you often login to the Pokemon Go trainer club and use the WiFi to design the environment, you might see an authentication error. Never try to log in and use the WiFi tethering simultaneously.

A glitch in the Application: In some cases, when the official developers of the game try to update the servers or the application, you might face an authentication error at your end. In such scenarios, you should wait till the developers upgrade the server or complete the maintenance.

Geo Issue: Pokemon Go is not supported in some countries. If you live in a country or location where Pokemon Go isn’t supported, you might see the authentication error.

Rooted Phone: If your phone is rooted, it is highly likely to be hacked. Hackers can easily access your personal information and install unauthorized apps on your phone. For this reason, Pokemon Go is not supported (in most cases) on rooted phones.
