There are a few common reasons why you may be unable to log into your Facebook account on your browser:
You are using the wrong email or password
Double check that you are using the correct email address or username and password associated with your Facebook account. It’s easy to accidentally type the wrong credentials, especially if you have multiple email accounts.
If you can’t remember your password, you can reset it by going to the Facebook login page and clicking “Forgot Password?” You’ll be able to reset your password after entering your email or phone number and answering your security questions.
Your account was disabled or deactivated
Facebook may have disabled or deactivated your account due to suspicious activity or violating their terms of service. You would have received an email notification if this was the case.
To reactivate your disabled account, you’ll need to contact Facebook and work with them to regain access. This may involve confirming your identity by providing copies of your ID.
You are logged in to the wrong account
Your browser may be automatically logging you in to a different Facebook account that uses the same email address. This can happen if you have multiple Facebook accounts.
Try logging out completely by clicking on the down arrow at the top right and selecting “Log Out.” Then log back in with your correct email and password. You can also try opening an incognito or private browsing window and logging in there.
Your browser’s cookies and cache are corrupted
Corrupted cookies and cached data can prevent you from logging in even with the right credentials. Try the following steps to clear your browser data:
- On Chrome, go to Settings > Privacy and Security > Clear Browsing Data. Select cookies, cached images, etc. and clear data.
- On Firefox, go to History > Clear Recent History. Select cookies, cache, etc. and clear data.
- On Safari, go to Preferences > Privacy. Select Manage Website Data and remove Facebook data.
After clearing cookies and cache, reboot your browser and try logging into Facebook again.
Your browser is incompatible or out of date
An outdated browser can sometimes lead to login issues on Facebook. Make sure you update your browser to the latest version and try again:
- Update Google Chrome to the newest version.
- Update Mozilla Firefox to the newest version.
- Update Apple Safari to the newest version.
- Update Microsoft Edge to the newest version.
If updating your browser does not resolve the login problem, your browser may be fundamentally incompatible with Facebook. Try logging in with a different modern browser like Chrome or Firefox.
Your ISP or network is blocking Facebook
Corporate networks or internet service providers will sometimes block Facebook due to security policies. Switch to your phone’s mobile data or another trusted wifi network and see if you can log in that way.
If you can log in on mobile data but not your home network, contact your ISP to ask about Facebook being blocked. In a corporate environment, speak with your IT department to request access.
Facebook is down or having a widespread outage
In rare cases, Facebook itself experiences downtime that prevents people from being able to log in. Check downdetector.com to see if Facebook is having an outage.
Major outages are usually resolved within a few hours. Try logging in later or following Facebook’s public communications on the issue.
Your Facebook account was hacked
If none of the above solutions worked, it’s possible your Facebook account was compromised. A hacker may have changed your password and enabled two-factor authentication to lock you out.
To recover a hacked Facebook account, you will need to submit ID verification and use Facebook’s hacking recovery process. This involves entering a special code they send to your email on file or submitting documents to prove your identity.
You have third-party account access enabled
If you previously gave permission for another app or service to access your Facebook account, they may be logging in and preventing you accessing your account in the browser.
To revoke account access for third party apps and services:
- Log into your account if possible.
- Go to Settings > Apps and Websites
- Click “Log in with Facebook” and remove any unfamiliar apps.
Once permissions have been revoked, you should be able to log in directly through Facebook again.
Multi-factor authentication is turned on
If you enabled two-factor authentication or other multi-factor login requirements for enhanced security, you may need to enter a code from your mobile device or backup codes to log in.
If you no longer have access to these codes, you can get back into your account by following the two-factor authentication recovery process and entering a special security code Facebook sends to your email.
You are using a VPN or proxy service
Facebook may block logins from certain VPN IP addresses or shared proxy networks due to suspicious activity from those services. Try disabling your VPN and logging in directly through your internet provider.
In some cases, you may need to contact your VPN or proxy provider to have them refresh their IP addresses due to bans from Facebook. Using a more reputable commercial VPN can also resolve login issues caused by cheap or free proxy services.
Your computer clock is inaccurate
If your computer’s clock settings are set to the wrong time, it can sometimes create issues logging into sites like Facebook. Double check that your operating system has the right current date and time based on your timezone.
You can also try manually setting the time on your computer or device to see if that allows you to log in. Inconsistent clocks can cause login tokens and other data to become out of sync.
You have automatic logins enabled
Facebook and many browsers allow you to enable automatic login so you don’t have to enter your password each time. However, this can occasionally prevent you from logging in manually.
Try turning off automatic logins in your browser settings and Facebook app settings. You can then attempt to log in manually again with your email and password.
Your browser has unauthorized extensions
Browser extensions or add-ons, even from legitimate sources, can sometimes interfere with Facebook’s interface and cause login problems.
Try disabling all extensions temporarily in Chrome or Firefox and attempt to log in again. If that resolves the issue, you can enable your extensions one-by-one until you identify any problematic ones.
Also check for unknown or unauthorized extensions that may have been added without your knowledge by adware or malware.
You are restricted by login approvals
If you have enabled Facebook’s login approvals from specific devices feature, you may be blocked from logging in on a new device.
You will need to add that device to your approved list. Log in from a device that is already approved, go to Settings > Security > Login Approvals, and add your new device.
Your account was Memorialized
If your account was Memorialized after being reported deceased, you will be unable to log in. Only verified immediate family members can request temporary account access in this situation.
Contact Facebook through their special request form for Memorialized accounts if you believe your account was incorrectly reported deceased.
Conclusion
Troubleshooting Facebook login issues requires methodically checking different devices, browsers, settings, connections, and account recovery options. Start with simpler solutions like updating your browser and clearing cookies and cache. For ongoing login problems, you may need to work with Facebook support for help regaining access to your account.
