Possible solutions for Facebook authentication failed

Check connection

It may sound a little silly but whenever you are facing a Facebook Authentication Failed error, first you should check the internet connection. If you are using mobile data, switch to Wifi and see what happens.

Clear Cache and Data

If you see that internet connection is not a reason for Facebook Authentication Failed error, then the next step is to clear both Cache and Data of the Facebook app. To do that, go to Settings > Application Manager > All tab > Facebook > Clear Cache and then Clear Data.

Many people have found a solution following this step. But if it does not work for you, then follow the next step.

Reinstall the Facebook app

If both the above steps do not work to fix Facebook Authentication Failed error then uninstall the Facebook app. Then re-install the current version of Facebook going to the Play Store if you are an android user. After the installation is done, reboot your phone and try to log in. It should fix the issue.

In most the cases, Facebook Authentication Failed problem occurs because of an obsolete version of the Facebook app.



  1. I can login using IE browser but not with android phone’s facebook application. I can successfully loin by Windows phone. I have tried reinstalling the same but not working.

  2. None of above work. Have used macbook’s, iohone, android phone. All do 100% the same and kick you out when you do anything to do with any settings!


  3. Ahhhh anyone got a resolve to this?

    Does not matter what device I use of what connection I use, same issue, will log me out at settings area on Facebook?


    They have ZERO customer service to contact!

  4. I am having the same issues above. Facebook Authentication Failed Every time I tried to accessing any settings. Im getting frustrated. Please Help!

  5. I have the same issue above. But I suggest to open your facebook during midnight or 12am above to 5am. It will works like nothing happened. You can post, navigate your setting, log in to browser etc. But morning above, I faced again the same issue. I can’t even log in to browser nor post a status update. I guess someone is reported my account. Anyone would help us?

  6. I am having the same issue. I even reset my password, and deactivated, then reactivated my account. I can sometimes see my timeline and only share, like, and comment on posts. I can’t post anything new though (it says I am not authorized). And anytime I try to go into any settings (profile and security), it kicks me out with the authentication error. On the computer, it does a continuous log in loop like I don’t exist. If I check my email from Facebook (them telling me I logged on from an unrecognized source and to verify– when I finally get the app to “work”) it goes to a page that doesn’t exist. When I uninstall the app and reinstall it, it makes Facebook do an app update. Something tells me my recent phone update and this app update are correlated, but I’m not sure. The fact that I can’t even log on to a browser is frustrating. Get it together, FaceSpace!

  7. Same prob mam.
    Reinstall app but still fb authentication prob..can’t logged in by chorme and uc browser.. Pls help..

  8. It wasnt easy. There is an option on your account but of course I kept getting hacked. If you can get the the help center and put hacked in the search bar, it will bring up steps to follow. I also googled and facebok provided a link. If I could post pics on here I would. This was aweful!!!

  9. I’m having the exact same problem you described. At least I know it’s not just me. I’ve written to FB support many times, zero rrsponse. I was able to create a data recovery issue and open a ticket for resolution, but they don’t respond by human, being, only once but he disappeared. They may be doing this on purpose. It’s wrong because our data is there and we have no control over it. Please let me know if you have any success. Facebook has the worst customer service I’ve ever seen. Ironic that this page has a “like this on Facebook” button.

  10. Guys, I tried EVERYTHING for weeks multiple times and daily and had no luck googling for a resolution. I even came back here to see if anyone had found a solution. Yesterday, I reported my account hacked and it is fixed. I had to try again and to report it because it obviously kept kicking me out. But the problem is resolved!!!

    1. Same here for weeks now. I cant do anything much on FB. I can log on through my app but can’t access any of my account settings. I cant log in anywhere else. I can only post if I have a pic or share a post. SUPER frustrating.. cleared cache.. deleted and readded app.. even got a new phone with a new FB app.. still nothing. Reported it to FB.. they responded and I got FB Authentication Failed when accessing their response.

    1. That is exactly what happened to me. Can’t make a post without a pic, can’t go into any settings and can only log in on the app.

  11. i tried all these but it doesn’t work at all. i want to deactivate my FB account temporarily but once i click the security it logout at once without clicking the deactivate and Facebook authentication failed appears. please help me with this problem. Thank you.

  12. Tried everything related to the authentication failed topic and still can’t log in in the app (or just use some features anyway) and not even from laptop. Any suggestion? Thank you very much
