8 Ways to Fix Pokémon Go Unable to Authenticate

Fix 1 Restart Your Mobile Phone

If you're experiencing problems playing games on your phone, the first thing to do is restarting it. Most of the time, it has worked for me when I've had issues with Pokemon Go and other applications, so give it a chance!

After restarting, relaunch Pokémon GO to check if you get an error notice that says "Pokémon Go unable to authenticate iPhone." If not, have fun playing. If yes, be sure to go through the solutions below!

Fix 2 Verify Your Account

Though it's conceivable that you made a mistake, the most straightforward solution is to authenticate your account. Take the following steps:

• 1. Go to the official Pokemon Go website in your browser.
• 2. Go to the login area now.
• 3. Then, after entering the required information, confirm and accept the terms and conditions. Go to your profile area and select "Pokemon Go settings" from the drop-down menu.
• 4. If a notice appears in front of you with the wording "Great! You're all prepared to play Pokémon GO. Other settings may be altered in the Pokémon GO app," you can begin playing the game.
• 5. If you don't see the notice, you'll need to authenticate your account before starting the game.

Fix 3: Check for the Server Issue

The server may be momentarily unavailable or undergoing maintenance at any time. If this is the situation, wait until the server is entirely operational before retrying the game.

It would be best if you went to verify the server's status. Otherwise, you may check their Twitter page to see if there is any new information on their server or if they are performing any maintenance. If the server doesn't cause the issue, you should try one of the other options.

Fix 4: Update the Game

The error: Pokémon Go unable to authenticate ban can also occur if the game software is outdated. Fortunately, Niantic distributes game updates regularly. As a result, you should consider upgrading Pokemon Go to the most recent version and seeing if it solves the problem.

On an Android smartphone, do the following:

• 1. Look for Pokemon Go on the Google Play app on your smartphone. You'll find the available update under the game.

• 2. Please put it in place and check whether it works.

  

If you're using an iOS device, you'll need to:

• 1. Go to the Apple App Store. Then select "Updates" from the drop-down menu.

• 2. You'll find an update for Pokemon Go there if one is released. Click the Update button, and the process will be completed instantly.

  

Fix 5: Clear Data and App Cache

You may not believe it, but your cache might occasionally cause the Pokemon Go unable to authenticate please try again problem. It's simple enough to correct, though: delete your old data, and you'll be good as new! Give it a shot. It's straightforward and only takes a few minutes. Here's how to do it:

On Android:

• 1. Go to Settings and select Apps to find what you're looking for.
• 2. Check out Pokemon Go in the applications department now.
• 3. Open the information for the Pokemon Go app now.

• 4. After that, select Clear Cache from the drop-down menu.

  

• 5. Now relaunch Pokemon Go to see whether the problem has been resolved.

If you're using iOS:

• 1. You'll need to remove the app first, restart your device and reinstall it.

  

• 2. Open the game now and see if you get the notice "Unable to authenticate, please try again" or not.

Fix 6: Disable Data Usage Restrictions

How do you authenticate Pokémon GO? If you're experiencing trouble with Pokémon GO not working because of an Unable to Authenticate issue, one remedy is to turn off any data use limits on your smartphone.

• 1. To do so, go to Settings > Cellular or Mobile Data > Restrictions and turn it off.
• 2. Try relaunch Pokémon GO once you've deactivated the Restrictions option, and it should operate as anticipated.

Fix 7: Check Your Phone is Rooted or Not

Determine whether your Android or iOS device has been rooted or jailbroken. Pokemon Go does not support a rooted/jailbroken smartphone. If this is the case, your device must be changed.

Here's how to use the Settings app to see if your phone is rooted:

• 1. Select "About phone" > "Status information" > "Phone status" from the Settings menu.
• 2. Your smartphone is not rooted if it has an official phone status. Instead, your phone has been rooted if a custom tag is on the screen.
