A linked account is an approved online account that you link to your Facebook account. This means that when you log in to the linked account, you will be able to access your Facebook account without logging in to Facebook.
You can link your Facebook account to a variety of other online accounts, including accounts with Google and Yahoo!. To see a full list, click on the drop-down menu in the "Linked Accounts" section of your Account Settings.
To add or remove a linked account, navigate to "Linked Accounts" section of your Account Settings page. Click "change" to see a list of all of the accounts that are currently linked to your Facebook account.
To link a new account, select an account type from the drop-down menu and click "Link New Account." Enter your Facebook password in the box that appears and click "confirm." Another box will appear asking you to sign into the account you wish to link (for example, your Gmail account).
To remove a linked account, simply click the "remove" button located next to the account.
Linking another online account, such as a Gmail account, to your Facebook account allows you to access Facebook whenever you are logged in to that other account. Thus logging into your Gmail account would also log you in to your Facebook account.
If you feel you have received this email in error, it is possible that someone is trying to gain access to your account without your permission. Follow the steps provided in the email to secure your account.
Please adhere to the following guidelines to help ensure the security of your account in the future.
Password Protection: You should select a unique and complex password for your account and keep this entirely to yourself. Be sure that you use a complex string of numbers, letters, and punctuation marks that is at least six characters in length. It should also be different from other passwords you use elsewhere on the internet.
Private Browsing: Please make sure that you log out of your Facebook account and quit your browser when you’re done using the site. This is especially important when using a public computer or someone else's mobile device. You should also never check the "Keep me logged in" box when logging in from a public computer, as this will keep you logged in even after you close your browser window.
Secure Email: Since anyone who can read your email can probably also access your Facebook account, you should make sure that any email addresses associated with your account are secure. To ensure security, you should change the password for all of your email accounts and make sure that no two are the same. By varying your passwords, you can greatly decrease your account’s risk of being compromised in the future.
Security Question: If you have not done so already, you should add a security question to your account from the Account Settings page. You should choose a question and answer that you will remember, and no one else should be able to answer the question that you choose.
Log in at Facebook.com: Make sure that when you access the site, you always log in from a legitimate Facebook page with the facebook.com domain. Do not click any unfamiliar links and do not run any executable files (files ending in .exe) on your computer without knowing what they are. If something looks or feels suspicious, go directly to www.facebook.com to log in.
Run Anti-Virus Software: If your computer has been infected with a virus or with malware, you will need to run anti-virus software to remove these harmful programs and keep your information secure.
