  • If you have android phone make sure to update the OS to be 4.4 or above
  • Required resolution to run the game: 720×1280 pixels


  • iPhone, that is lower than the model 5s will not be supported. You should use iPhone 5s or above.
  • Make sure to update the iPhone to be iOS 9 or above

Either its android or iOS, having a strong internet connection with 3G or 4G or Wifi is required. To play the game, GPS and location services must be on.

Pokemon Go Do Not Support The Rooted Or Jailbroken Devices

Pokemon Go wants to keep the game apart from bots and scarpers. These all require the root to be manipulated. If they allow legit players to be played on rooted and jailbroken devices, they may lend a path to hackers. It’s the reason why it bans the rooted or Jailbroken devices.

However, there is another way to get around this problem. Not everyone who has rooted the devices is cheating the game. They may have rooted the device for some other reasons too.

How To Play The Pokemon Go On a Rooted and Jailbroken Device?

If you have rooted android device then running Magisk (with root turned off ) on it will help you to pass the SafetyNet API’s test. (Pokemon Go uses Google’s SafetyNet API test to find out the rooted users).

If you have both Xposed framework and Magisk installed on your Phone, Chances are you may get a message “payload validation failed” from SafetyNet. If this is the case, try disabling the Xposed and reboot the phone. It will pass the SafetyNet. If it fails again, then this video tutorial may help you further.

For the iPhone, apps like Xcon or Masterball intelligently hide the jailbreak detection.

If you use multiple Google accounts on your phone, the chances are the game might take the different one on your phone to login Pokemon Go. Thus it causes the error unable to authenticate. To fix this issue, remove all other Google accounts and keep the one you used to play the Pokemon Go.

5) Remove The Other Device If Any From Google Setting

This fix is used for Android devices. If you use another device to log in your Pokemon go or some other app, the device will be added to your main Google account. So if you receive the login error, you can fix it via deleting another device id from your account. It should be done through accessing the Google setting on your android.

After completing all these steps, try to login to your Pokemon Go app through Google login and start playing the game.

6) Problem With PTC account? Link Google or Facebook Account

Majority of users who play Pokémon Go have registered their accounts using their Pokémon Trainer Club account. As several thousands of players playing this game online, the server load of PTC website always seems to be high. It’s the reason why PTC website dies more frequently than the one that handles the Google accounts during the peak hours. Hence it’s completely logical to get the error.

You can check your PTC Server Status by clicking here.

To get rid of these login errors, link your PTC account with Google or Facebook. Linking Google account or Facebook account will carry all your data as in PTC account. Nothing will be changed except your errors!

8) Are You On iOS 9 or iOS 10?

For those players who use iOS 9 or iOS 10 with pokemon go version of 1.73.3, seeing the login issues is the common one. As a solution, if you use iOS 9 you need to upgrade to iOS 10. According to Niantic labs using subsequent sign-in attempts will lead you to enter into the game. The working on this issue by Niantic labs is still on the process.

7) Check Whether You Got A Ban

After checking all the tweaks and tricks given here and still you receive the unable to authenticate, the chances are you may get banned.

Niantic Labs bans the players who seem to cheat the game using bots, GPS spoofers and third-party software that worked with a Pokemon Go backend. Your account might also be flagged for deletion if you ever used falsifying locations and emulators. Users who get the permaban will receive a mail stating the deletion of an account.

If you haven’t violated any of the Pokemon Go TOS and you think this ban has happened mistakenly, you can submit an appeal form by clicking here. Once you submit the form, you will get an auto-generated message confirming the ban. Wait for them to reply.

    I tried what you told me and I Still get the unable to authenticate error message I want to be able to play this game so bad as it is my favorite game I have written to niantic and did everything they told me and nothing worked either I just want to play

  2. Kerim October 16, 2017

    One other thing that can block Pokémon from authenticating is when you have restricted data usage of Googe Play Store in Settings -> Data usage -> Google Play Store. If “Restrict app background data” is on, you cannot log in to Pokémon Go without WiFi.

    I am also experiencing problems on a phone that I have on lend, because my own phone broke. This phone somehow shows “uncertified” in Google Play Store (the app itself) -> Settings, under “Device certification”. So far I have not been able to solve this issue, but I suspect that this is what is preventing Pokémon Go to continue on this particular phone.

    Sorry for the very late reply. “uncertified phone”. Does this phone is rooted?

  4. Sukanya Roy September 18, 2018

    This also happens when you (accidentally) left your VPN running!

  6. Jessica strong October 24, 2019

    Be that as it may, here and there they see “Pokémon Go unable to authenticate” error while login Pokémon Go Trainer Club.

  7. Robert October 24, 2019

    OK, I struggled with this error for a couple weeks. Nothing I tried seemed to work. Then I came across an article about changing your IP address and it struck me. I started having this issue after turning on a VPN app on my iphone. Sure enough, after turning the VPN off I was able to connect and open Pokemon Go.
