How can I make sure I don’t lose access to my account?

In the event that you forget your password, you will need to request a password reset. This password reset email will only go to email addresses that you have confirmed on your account. As such, if you are unable to access the email addresses on your Facebook account, you will not be able to receive your password reset email and may lose access to your account completely. You can prevent this situation by taking the following measures:

• Add a secondary email address to your Facebook account.
• Add a security question to your Facebook account.
• Make sure email addresses on your Facebook account are active (you are able to access them).
• Maintain accurate information on your profile, such as name, date of birth, and email addresses. This helps us locate your account, should you lose access to it.
