Another person has been using my computer and has mixed up my Facebook. She has put in her information to get to her Facebook account and has knocked mine out. How can I get my Facebook account back on track ? Apparently she has put in her password and knocked mine out. How do I correct this?

Please do not put personal information on this site. I would recommend you contact facebook, as we do not have access to your information.

You can deactivate that account.

1. Click the account menu at the top right of any Facebook page.
2. Select Settings.
3. Click General in the left column.
4. Choose Manage your account and then scroll down to click Deactivate your account.

But if you linked your personal account with the page. you must change the administration power to any other personal facebook account first. like your page from that account. then transfer the admin role to that personal account and delete your old account.

Hmm... someone might have hacked your account. Try checking your inbox from the email provider your Facebook account is associated with. For example, if your email address has a domain name of yahoo.com, then log in to Yahoo, check your inbox. Facebook sends you an email right away if your Facebook account was hacked. The email they send informs you that your email address was replaced with a new one. Then it asks you if that is your own doing, you can just ignore it. But since you suspect someone is using your account, then that person might have replaced your email address with his. If that is the case, then there's an option in that email Facebook sent you to 'let them know' or 'secure your account'. Click on it. If you're successful, you should be able to get hold of your account back. And Facebook system will even prompt you to change your password.

Moral of the story? You should not give any of your email addresses to anyone. Not even to family members, relatives or friends. If the computer you're using is also used by other people and there are no separate user accounts for each [meaning everyone can log into that computer as administrator then one safety tip is to NOT save your password in Mozilla Firefox. If you do and another person who is Internet savvy clicked on the browser's Tools menu [Tools>Options>Security>Saved Passwords] when you're away, then that person can hack your account/s. If you're the owner of the computer and you're sharing it with other people, better create a guest account or user accounts for each person who uses your computer, but make sure you're the administrator of your own computer and that each of you has his/her own password when logging on to the computer.

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 today more 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.

Reset Facebook Password
Suddenly you attempt to login to your Facebook profile.
Perhaps you have simply forgotten your password or worst case your Facebook account security has been compromised.
Having had this happen to me, I can help you reset your Facebook password and restore your peace of mind.
You will be back networking with your friends, family and coworkers in no time.
Go to your computer bring up the Facebook login screen like you normally would.
Do not fill in any information.
Click on the link above your Facebook user name and password that states forgot your password. This brings you to a different screen.

Fill in the email address associated or on file with your Facebook account.
If you cannot remember, keep trying different email addresses until you do.
Click enter and a Facebook reset link will be sent to your email so you can recover your password. It usually takes up to 5 minutes.
Check your spam email folder if the email does not appear in your inbox.
Click the link in your email and answer any security questions by Facebook.
This brings back to the Facebook website.
Reset your password with a phrase you will remember mixed in with 1 to 2 numbers or more. Record this in a notebook or on a safe place.
Use a different password than you would for your email.
This decreases your chances of having both websites compromised.

Fro my research on your topic it seems a lot of people have had the same problem. I also read that Facebook took this feature option away.

Want to set up a business presence on Facebook but don’t want to have a personal presence? No problem! A little known feature of Facebook is the ability to create business accounts. However if you already have a personal account, keep in mind that you cannot create a separate business account. However if you would like to avoid setting up a personal account and would like to keep things professional, you can take a few steps to get things configured.

From the business account you will be able to manage Facebook advertising campaigns as well as Facebook Pages. In order to get your business account set up, all you’ll need to do is create a Facebook Ad or create a Facebook Page. After you’ve created the page or advertisement, Facebook will ask you to enter your login information or the option to select “I do not have a Facebook account”. At that point all you need to do is enter your business email address and date of birth. That’s it! Now you have a business account on Facebook. One thing that you should keep in mind is that if you have a personal account and go through this process, there is a very good chance Facebook will shut down both accounts. In other words: don’t create multiple accounts. I have received multiple emails from people that don’t want to set up personal accounts though so for those individuals that have not explored Facebook, you can proceed to set up a business account.
While I think advertising on Facebook or creating a page doesn’t make much sense without thoroughly understanding how Facebook works, the company has at least provided the option for those that don’t want a personal account.

From Facebook's Security FAQs...

I need to report an impostor profile. If someone has created an account to impersonate or imitate you, pleas... If someone has created an account to impersonate or imitate you, please go to the impostor profile and click "Report this Person" in the left column. Check the "Report this Person" box, choose "Fake Account" as the reason, and add "Impersonating me or someone else" as the report type. Be sure to add a valid web address (URL) leading to the real profile so that we can review the information. http://www.facebook.com/help/?faq=14240

Facebook accounts get hacked either to steal users information or sometimes to steal their facebook poker chips or other virtual currencies. You can write to [email protected] and explain your situation and they will reset your password after confirming some of your personal information.
