Today, while attempting to launch Pokemon GO as usual, I encountered an unexpected issue. The application became unresponsive and displayed the message, " Authentication failed. Please try again." Now, I find myself seeking a viable solution for this predicament.

I hesitate to proceed without resolving this matter, as crucial data is stored within the game, and I am concerned about potential unauthorized access. Any guidance on how to address this problem would be greatly appreciated.

Part 1: Why Pokemon GO Unable to Authenticated

The author sometimes couldn't authenticate when he wanted to open Pokemon GO.

1 The Registered User Name or Password is Incorrect

Most likely, you entered the wrong username or password when registering for the Trainer Club. Also, I originally registered with a Google account or Facebook account instead of the Pokemon Trainer Club account, but I misunderstood and tried many different methods.

2 Wi-Fi and Tethering are Used Together

One of the reasons why Pokemon GO can not be authenticated is that you are using a Pokemon Trainer Club account and you are using Wi-Fi or Dethering in your Internet environment. Also, Wi-Fi problem may cause the problem of Pokemon GO routes not working.

Also, if you use Wi-Fi or dethering at home and log in to Pokemon GO, it may be displayed that you cannot authenticate when you go outside.

Occasionally, the Pokemon GO app does maintenance, so there are times when the app doesn't open, and sometimes even if you log in successfully, you may face Pokemon GO failed to detect location problem.
