There is a list of eight solutions. You can try all the steps and one of them is definitely going to work to solve the Pokemon Go Unable To Authenticate error. So without further ado, let’s get right into it.

Solution 1: Check Airplane Mode Status

It’s pretty obvious from the very title that you need to switch your airplane mode on and off to get this solution to work. Now generally most of us have a clear idea about how to switch the airplane mode on and off because we often do it.

But to those of you who do not have an idea about this feature of your phone, here are the steps to do it (feels silly to describe it):

Step 1: When you are displayed with the error message on opening the app, exit the game, and close the app.

Step 2: Go to the Settings of your phone and switch the airplane mode on. You can also find easy access to airplane mode if you check in your notification bar panel by pulling down or up (depends on your phone model).

Step 3: The next step is to restart the game Pokémon Go.

Step 4: Now drag your notification bar panel and switch off your airplane mode. You can simply do this by tapping on the airplane icon. It’s easy to spot.

Step 5: Try to login into your game once again by entering your password.

This basically completes the process. If you can log in then there is no problem. However, if it is unsuccessful then there is no need to be disheartened. You can proceed to the next step. There are seven more steps to go, so there is no need to panic.

Solution 2: Check Pokemon Go Server Status

The next step is checking the Pokemon Go Server Status. There are generally no steps to be undertaken in this solution. Since this is a very popular game and has players all over the world it can happen at times that many players are playing the game at the same time.

This can cause some problems with the server and result in the “Pokemon Go Unable To Authenticate” error which is in the spotlight today. The servers go down when several hundreds of players try to log in and play at the same time so it is important for you to check out their server status for once to see if their servers are working or are they down.

If you find that they are down then you need to patiently wait because their team is working on it and the server will be up in a few hours. But if you find that their server is not down then you can proceed to the next step.

Solution 3: Create a Force Stop and Again Launch Game

You can also try to force stop the game and launch this game again. That works for some players. Now to do this then you have to follow the following steps:

For Android:

Step 1: Go to the settings of your phone.

Step 2: Find the tap ‘Apps‘ and click on it.

Step 3: Find ‘Pokemon Go‘ and open it.

Step 4: Click on the ‘Force Stop‘ button and relaunch the game.

For iPhone:

Step 2: Launch the game again.

If the problem or error is not solved when you relaunch the game then proceed to the next step.

Solution 4: Try to Login with Google Account

A very common reason behind this ‘Pokemon Go Unable To Authenticate‘ error is caused by the server you choose to log in from. If you are trying to log in through a PTC server then it is likely that you will be shown the error message.

Many Pokemon Go users like to use the Pokemon Go Trainer Club account. If your error is persisting, you can do the following steps:

Step 1: Try to log in from your Google Account. At this age, we all have a Google Account. It’s impossible to function without it.

Step 2: If you try to login from your Google Account and the error message is gone then you can start playing your game.

Step 3: If it is still displaying the Pokemon Go Unable To Authenticate error message then proceed to the next step.

Solution 5: Check your Saved Password

This is for those who have several Google accounts. You can choose which account you are playing Pokemon Go from. If your present account is not functioning then you can switch accounts. This has helped some of the problems in solving the error into consideration.

Solution 6: You Clear Caches on Your Device

The next solution for the “Pokemon Go Unable To Authenticate” error is to clear the caches of your device. To do this you can follow the following steps:

Step 1: Go to the settings of your phone.

Step 2: Find the “Apps” tab and open it.

Step 3: Search for the Pokemon Go app. Once you find it, open it.

Step 4: You can find the ‘Clear Cache‘ option here. Click on it and confirm.

Step 5: Try to clear the data too. It is usually present next to the clear cache option.

Step 6: Start the game again.

If the error message is removed then you are set to play the game. Unfortunately, if it still persists then go on to the next solution.

Solution 7: Are You Using iOS 9 or iOS 10

If you are an iPhone user then you need to check if you are on iOS 9 or iOS 10. Pokemon Go Version 1.73.3 is compatible with both. But if you are on iOS 9 and facing the error problem then you can proceed to upgrade your iOS to iOS 10.

After upgrading your system, try to login into your game again. If the error message is not displayed then well and good but if it is still there then read on to the next solution.

Solution 8: Go to the Pokemon Support

If all the above options fail and you still get that error message on your phone screen then the best option for you is to contact the Nintendo Team for help.

You can visit their support page and post your problem. They have excellent customer support service and they will surely sort out your problem for you.
