Hi

Just open Facebook app and open it fill your login detail.
If forgot password click on forgot password and reset the same via SMS code confirmation.

You need to provide the proper e-mail address and password for the page. If you forgot the password, then use the Facebook recovery tool.

and you might want to look at:

Hi
If you are being blocked then it is likely that you are not entering the login details that Facebook is expecting, whether they have been satisfactory in the past or not.You could try this, go to the login page here:,
Facebook
just under where you input your password you can click on "forgotten password". This takes you to a page where it says "find my account" where you can enter "Email, Phone, Username or Full Name". Try entering one of these (My email gave the best result for me) and follow through the instructions to reset your password so that you can access your account.
If this does not work there are a number of options here depending upon what you have lost, ie you can't log in, your facebook page has been locked and you can't change it, or it no longer appears to exist. I could go through them all but it has already been done here:
How To Recover Your Facebook Account When You Can No Longer Log In
It details the methods you can try depending upon the exact circumstances.
Hope this is helpful, if so would you please register that with Fixya
Cheers

Have it reset again.

If you can't log into Facebook and need to reset your password:

1. Go to the login page at https://www.facebook.com
2. In the top right, click Can't log in?
3. Type the email, phone number or username associated with your account, then click Search and follow the on-screen instructions

Point your web browser at http://www.facebook.com

If another account comes up, log out of it by clicking the little down arrow in the upper-right then clicking "Log Out."

If you then still can't log in to your account, click the "Forgot your password?" link located just below the password box on the login page.

If you're getting an error message, exactly what does it say?

You will first need to log out of the other person's account. Just click the small gear icon in the top right and click log out. Once you log out you can then enter your email and password to log in.

Just don't forget to log out of your account once your finished or others will be able to access your account on that computer.

Hope that helps!

you can reset you password by visiting
https://www.facebook.com/recover.php

1- Enter your email where it says "Option 1"
2-Click Search button
3- you'll be asked to enter two words for the security check
4-after that an email will be sent to you in order to reset your password

that problem sounds like your phone. But you can call customer care for att and they will tell you weather you need to replace your phone.

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!
