I am using the correct email and password wont log in why ?

If you gave him your password and your username for your email account or for your messenger account then he can log in to your account and change the password to one only he knows. If he can get into your email he can read all your old emails. If you use the same password for multiple accounts, he can keep guessing at what accounts you might have and try the password. Even if you have accounts that don't use the same password but use your email address to log into, he can try to log into those with your email address and say he doesn't remember your password and they'll email him a new one.
Sounds like you're screwed. Call your ISP (Internet service provider)

Be sure you are using the correct email address and password. If you are unsure, click the link to Forgot your email address or password? from the PayPal login page.

When Facebook was founded on February 4, 2004, it defined its mission as "Giving people the power to share and make the world more open and connected."

With the widespread success of this social networking website todaymore than 500 million regular users as of April 2011 it may meet that goal for many.

When a Facebook user can no longer access an account, it can be frustrating, but there is typically a reasonable explanation.
Cookies/Cache

Facebook suggests that any user who can't access their account should clear cookies and cache on their computer as a first step.

This will help remove old and unneeded files from your computer, and will sometimes help your computer to run faster, as well as allowing access to Facebook again.

Once cookies and cache have been cleared, you should type "m.facebook.com" into the address bar on your computer.

Avoid using any old bookmarks or links to visit Facebook for this first visit after clearing the cookies and cache.

Password Incorrect

If you attempt to log into your Facebook account with an incorrect password, you will be unable to access your account.

Even if you have the correct email address, that is only half of the log-in equation, and the correct password is absolutely necessary to log into the site.

If you may have entered the wrong password, enter it again, taking care to get each character correct.

Passwords are case sensitive, so all capital and lowercase letters and any symbols must be entered correctly.

If you have forgotten your password, you will need to click the "Forgot Your Password" link to recover your account and create a new password.

Account Closed

Facebook reserves the right to close accounts that they have determined are in violation of their terms of service.

If Facebook found that your account contained inappropriate content, did not represent a real person, or violated Facebook rules in some way, the account may be closed, leaving you unable to access it.

If your account was closed for one of these reasons, your login will fail and you will be provided with a link to Facebook's "Confirm Your Identity" page, where you can read about typical reasons for account closures.

Email Login Incorrect

If you have entered the incorrect email address, you will be unable to log into your Facebook account.

The email address that you use to log into Facebook is case sensitive, just as your email address is. If you fail to capitalize a letter or forget to insert an underscore that is part of the email address, login will fail.

If you cannot access your Facebook account due to an incorrect email address, double checking the address for correctness prior to logging in again will resolve the issue.

Compromised Account

If account information such as your email address or password is stolen, your account may be compromised.

If, for example, your account information is stolen, the person in possession of your log-in information can access your account and change the password so that you will no longer be able to get to your account.

If you think this may have happened, you must access the "Compromised Account" page on Facebook and follow steps to prove your identity and secure your account.

go to www.facebook.com
enter the email and password you used to register and click login. That should direct you to your facebook account. If you have forgotten your password, click on forgot password tab and request a new password. It will be sent to the email provided. From here you can sign in again using the new password

Hi, if you have typed your email in correctly, but forgotten your password, it comes up with a box (pink background / red border), stating your log-in name, and below that, your email. Just double check it's yours. If you have used a different email account to log into FB, then they'll be sending your password to the email account shown below your profile picture. Check that email address (if you have access to it). Also, if your own email is coming up, just double check the FB emails are not in your "junk / trash" inbox. You may have set FB as a blocked sender on your email account - you'll need to check that setting too (I can't help with that, as I don't know your email provider).

Hopefully that will sort your problem, let me know on here if it doesn't please?

1- Delete the email account from your phone and re-enter it.

2- Passwords are normally case-sensitive, make sure you are using the correct characters.

3- Log into your email account from a computer and confirm your password is correct and works.

Change your password at your computer, log in and make sure the new password works, then start with step 1 above.

use your email and the "Forgot Password" they should sent it to you.

1. first you can user the "forgot My Password" link and try again after the email was sent to you.
2. open Windows NotePad and type your password - this is to make sure you are typing it correctly.
3. copy the password- make sure you don't copy extra space at the end
4. try to log in by pasting what you copied.

another option is that Facebook has some login issues - try to wait a day and see if it continues
