How to Login to Your Account on Facebook From Someone Else's Computerby Steve Gregory
Logging in to your Facebook account from a friend’s computer will require a few extra steps if your friend has opted to remain logged in to his account. Selecting the Keep Me Logged In check box on the Facebook Sign In page enables a user to automatically access his account -- without logging in -- whenever he navigates to the Facebook website. Therefore, when you open Facebook on your friend’s computer, his Facebook account will open. You need to log out of your friend's Facebook account to access the Facebook login page.
Navigate to the Facebook website on your friend's computer.
Click the gear-shaped icon when your friend's Facebook account opens.
Choose "Log Out" from the drop-down menu to log out of your friend's Facebook account and automatically open the Facebook Log In page.
Enter your email and password in the appropriate fields and click "Log In" to open your Facebook account.
Select the gear-shaped icon and click "Log Out" when you are finished using your Facebook account.
- Don't select the Keep Me Logged In check box on a public computer -- such as a computer at the library -- to avoid unauthorized access to your account.
