[2025] Pokémon GO Login Issues: Why You Can’t Sign In & How to Fix It

Struggling with Pokémon GO login issues in 2025? I've been there too. Many trainers find themselves stuck on the loading screen, greeted with strange error codes, or told their account doesn't exist.

The reasons vary for each case, and each one needs a different solution. Let's break down what might be happening, why it occurs, and how to fix it.

Login problems in Pokémon GO can show up in many forms, from error codes to the game being stuck on the loading screen. Let's break down some of the most common cases and how you can fix them.

1 Pokémon GO Error 15: access denied

Error 15 usually happens when you log in and out of Pokémon GO too many times on the same device, especially with Pokémon Trainer Club (PTC) accounts.

The PTC login system has introduced stricter security checks — if you try logging in around 6–7 times in a short period, your device can get temporarily blocked.

Fixes that work

• Wait a few hours. The block normally resets on its own.
• Avoid rapid logins and logouts, especially with multiple PTC accounts.
• Link your account to Google or Apple. Error 15 tends to only affect PTC logins, so switching to a different login method helps.
• Using a VPN might give you a few more attempts, but the block will eventually catch up with your device.

2 "Failed to Sign In" / This account has failed to authenticate

This error often pops up when there are server-side issues with Niantic's login system or the cloud services it relies on.

For example, in June 2025, a major Google Cloud outage took down several services worldwide, including Pokémon GO logins. If that happens, there's little you can do on your end except wait.

Fixes that work

• Tap "Try a different account" and then return to your original login. For some players, this refreshes the authentication process (especially with Face ID or Apple login).
• If you normally use Google or Apple to log in, try switching temporarily and then switching back.
• Check Niantic's official status page or Pokémon GO's social channels to confirm if it's a widespread outage.

If you see this error while others are also reporting login failures, the problem is likely global. Your best option is to wait for Niantic (or Google Cloud) to fix it.

3 Pokémon Trainer Club won't load for login

If you're trying to log in with a PTC account and the page refuses to load, it's often caused by browser settings or cached data. In some cases, the issue may even lead to Pokémon GO crashing during login attempts.

Fixes that work

• Go into your browser settings, remove cookies for the PTC site, then try logging in again.
• Some apps don't play nicely if your default browser isn't Chrome. If you're using something like Samsung Internet, switch your default to Chrome and try again.
• On the login page, tap the three-dot menu → select info → cookies → trash can icon → delete cookies → close the page and retry.

These steps usually get the PTC login page working again. If it still won't load, wait a few hours and try again — sometimes the issue is on Niantic's end.

4 Can't sign in with Google / Apple account

If the Google or Apple login button is missing, the issue usually comes down to the age you entered when first launching the app. If you accidentally set your age below the legal requirement, the game will block those login methods.

In fact, if you just tapped through quickly, the game may think you're 1 day old, which obviously doesn't qualify you for a Google or Apple account.

Fixes that work

• Delete Pokémon GO's app data (or uninstall and reinstall the app).
• When you relaunch, set your birth year to 2007 or earlier.
• If you're under 18, note that some login methods may still have restrictions.

5 Pokémon GO account doesn't exist

This one is scarier: you try to log in, but Pokémon GO says your account doesn't exist.

Sadly, this often happens with PTC accounts, which have been hacked multiple times in the past. If your account was linked to PTC, a hacker could log in, unlink your other login methods, and even relink the account to their own email.

What you should do immediately

• If your account is still accessible, unlink PTC right away and switch to a safer method (Google, Apple, or Facebook).
• If you've already lost access, gather screenshots or old emails showing your trainer name, trainer ID, or account info.
• Contact Niantic Support directly. Sometimes selecting unrelated menu options (like "routes → something else") gets your request passed to a human.
• Try X support — many players report faster help there.

The hard truth

Niantic Support may refuse to help unless you can provide your current trainer nickname or email linked to the account. If a hacker changed those, recovery can be nearly impossible. Players in similar situations often report losing their accounts permanently.

Fixing login errors is one thing, but keeping them from happening again is even more important. Here are a few steps you can take to protect your account and make sure Pokémon GO runs smoothly:

• Unlink your PTC account

If you're still using a Pokémon Trainer Club login, it's time to let it go. PTC accounts are notorious for being insecure and have been the target of multiple hacks. Link your account to Google, Apple, or Facebook instead — these platforms are far more secure and less likely to cause “account doesn't exist” issues down the road.

• Regularly clear app cache

Pokémon GO stores a lot of temporary files, and over time, this data can get corrupted, leading to login errors or crashes. Clearing your app cache every so often keeps the game running smoothly and reduces the chance of sudden problems when signing in.

• Enable two-factor authentication (2FA)

Your account's security matters just as much as the game itself. Turning on 2FA adds an extra layer of protection by requiring a code in addition to your password when logging in. This makes it much harder for hackers to gain access, even if they somehow get your login details.

• Update Pokémon GO whenever possible

Niantic pushes out updates not only to add new features but also to patch bugs and fix login issues. If you ignore updates, you risk running into problems that have already been solved. Make sure you're always on the latest version of the app.

By following these simple steps, you'll save yourself from a lot of frustration and keep your Pokémon GO adventures running without unnecessary interruptions.

Sometimes, login issues aren't the only frustration — walking long distances can also be a barrier. Whether it's due to accessibility needs, bad weather, or simply a busy lifestyle, you might wish there was a way to enjoy Pokémon GO without physically moving around.
