How can I make sure I don't lose access to my account

Logon your facebook account pm another computer with another (a different) internet connection to verify your account. Error seems to be due to two devices on facebook at the same time on the same internet connection, e.g. your home internet.

Are you sure you're using the correct email address & password that you used as a login? Typing mistakes are a common reason for not being able to login. If you don't remember your password, you can have it emailed or sent as a text to your mobile phone (if you set up your mobile in facebook). On the facebook home page there is a "forgot your password?" link you can use.

Issue: i tried to log in to facebook from my phone and when i enter my info and click ok it only takes me back to home screen and says i need to log in. i tried loggin in on someone else\'s account and it worked. what could it be?

Causes and solution:

1) There are chances that the Facebook Account login account and Passwords has been mistyped.

2) There are also chances of the Facebook password hacked.

Note: I recommend you try logging into the FB account in the Computer and check if it is working.

If not the passwordis hacked and you need to answer the security question then get back the access. DON'T FORGET TO CHANGE THE PASSWORD AS SOON AS YOU LOGIN.

You can also check this link: http://www.facebook.com/mobile/ Use that application in the mobile and try logging using that.. remember to uninstall the previous application you're using before you're installing this.

The above following steps should resolve the issue.

Revert me if you have any problems or need more attention on this issue :)

I am now able to login to Facebook with my mobile.
I select the HTTP login at the bottom of the screen and then I had to re-enter my login info and I was able to get to my home page.
The only thing I did was on my java settings I selected the media profile...not sure if that was the reason why it wasn't working but it is working now! If you do get on, Book mark your homepage and then you shouldn't have any problems getting back to it in the future! Hope this helps!
