Can’t Log Into Facebook on PC? Fixing the “Access blocked: This app’s request is invalid” Google Error (2026)

You changed your Facebook password. Your phone still works, but the moment you try to log in on your computer, Facebook sends you to Google to “verify.” Then Google shows this:

Access blocked: This app’s request is invalid

You switch browsers and get the same error. It’s frustrating, but you haven’t done anything wrong, and this is usually fixable in about 15 minutes.

I ran into this exact problem after a password change, so this guide follows what worked for me and what I’d check first. If you’re worried about your account’s safety along the way, there’s a security section further down.

What’s actually going on

After a password change, Facebook often treats your next PC login as a new, unverified device. If your account’s primary email is a Gmail address, Facebook may route the security check through Google.

The error means Facebook sent Google a request that Google won’t accept. According to Google’s own help, only the app developer (here, Meta) can fix that specific error. That explains why:

• Changing browsers doesn’t help.
• Clearing cookies rarely helps.
• Resetting your Google password doesn’t help.
• Your Android or iPhone app still works, because the phone is already trusted and skips the Google check.

Step 1: Figure out which situation you’re in

Answer these three questions first.

Can you still log in on the Facebook mobile app?

• Yes: go to Step 2. This is the best case.
• No: skip to Step 5.

Is your primary Facebook email a Gmail address?

• Yes: that’s very likely the trigger, so Step 2 is your fix.
• Not sure: check in the app under Accounts Center → Personal details → Contact info.

Does the login screen offer “Try another way” or “Need another way to authenticate?”

• Yes: try that first (Step 3), since it’s the fastest route.

Step 2: The fix that worked for me (change your primary email)

This needs the mobile app to be working. Menu names vary slightly between versions, so follow the closest option you see.

1. Open the Facebook app (not the browser on your phone).
2. Tap the ☰ menu → Settings & privacy → Settings.
3. Open Accounts Center.
4. Go to Personal details → Contact info.
5. Add a non-Gmail email (Yahoo, Outlook, iCloud, Proton, or similar).
6. Open that inbox, enter the confirmation code, and verify it.
7. Set the new email as primary.
8. Only after the new email is verified and primary, remove the Gmail address.
9. Wait 10 to 15 minutes.
10. On your PC, log in with the new email and your Facebook password. Don’t click the Google button.

My result: I already had a Yahoo address linked alongside Gmail. I removed the Gmail address, logged in on my PC, and Facebook asked me to connect a passkey I had already set up on that computer. After that, I was in. No Google prompt appeared.

A safety note before you delete anything: never remove an email until you have another verified email or phone number on the account. Otherwise you could lock yourself out of future password resets.

Step 3: Bypass the Google prompt

On the screen that sends you to Google, look for:

• Try another way
• Need another way to authenticate?
• Get more help

Then use whichever option you have available: an email code, an SMS code, a recovery code, or an approval from a device that’s already logged in. Keep in mind that repeatedly clicking the Google button won’t work once that request is being rejected.

You can also try Forgotten password? on the login page and send the reset code to your new email or phone. For some people, this skips the broken Google step.

Step 4: Clean up the PC side (quick checks)

These rarely fix the problem alone, but they help you rule out side issues:

• Try a private/incognito window.
• Turn off your VPN and ad blockers for the attempt.
• Clear cookies for facebook.com and accounts.google.com.
• Sign out of extra Google accounts so only one is active.
• In your Google account, visit myaccount.google.com/connections and remove Facebook/Meta if it’s listed.
• If you use Google’s Advanced Protection, know that it can block third-party sign-ins.

Step 5: If you’re fully locked out

If the mobile app won’t let you in either, use only Facebook’s official recovery pages:

• facebook.com/login/identify to find your account and pick another contact method
• facebook.com/hacked if you think your account may be compromised

Follow the prompts on the page, including ID, selfie, or trusted-contact verification if they appear. Recovery can take time, and there’s no shortcut.

The security section (please read this)

People locked out of Facebook are prime targets for scams. Watch for these:

• “Facebook recovery experts” who contact you on social media or messaging apps. Facebook doesn’t do this.
• Anyone asking for your password, a login code, or a photo of your ID outside official facebook.com pages.
• Paid recovery services promising guaranteed results. Treat them as red flags.
• Look-alike links in emails or texts saying your account is “at risk.” Always type the address yourself instead of clicking.

I can’t promise that every locked or disabled account can be recovered. If your account was disabled for a policy reason, the fix may not be a login trick at all, and the official appeal is your only real route.

Lock it down after you’re back in

Once you’re in, spend five minutes making this less likely to happen again:

1. Keep a non-Gmail email as primary if that’s what fixed it.
2. Go to Accounts Center → Password and security and confirm your password, passkey, and phone number are current.
3. Save your recovery codes somewhere offline, not in your email.
4. Check Where you’re logged in and log out of any device you don’t recognize.
5. Turn on two-factor authentication if it isn’t already on.

Quick recap

Final note: Facebook changes its menus often, so the exact labels may differ slightly on your device. This fix worked for me and has been reported by others with the same setup, but it isn’t guaranteed for every case. If yours differs, the official Help Center is your safest backup.

If this helped you, share it with someone who’s stuck on the same screen.
