To protect yourself on Facebook, you need to make sure that the email address associated with your account is up to date. You can also change the username of the email address generated by Facebook (however, as this is only possible once, choose carefully).
Steps
Method 1 of 2: Website
Step 1. Log into your Facebook account
Step 2. Click the ▼ button at the top right
Step 3. Select "Settings" to open this section
Step 4. Change the settings associated with the email address
Two different types of e-mail addresses are associated with Facebook: the first is the contact and retrieval address, the second is the address created by Facebook itself. You can change both on this page, although the one generated by Facebook can only be changed once.
- Contact and recovery emails: Click on the "Edit" link next to your current email address. Click on "Add another email address", then enter the one you want to use. Open the verification message sent to this email account and follow the link to confirm it. This will become the primary email address that Facebook will use to contact you and help you if you need to recover your account.
- Email address generated by Facebook: click on the "Edit" link next to "Username" (the link is in web address format). To generate this email address, your username was used. As a result, if you change your username, your e-mail address will also be changed. The username can be changed just once. Also, if it doesn't include your real name, Facebook may revert to the previous one.
Method 2 of 2: Mobile Application
Step 1. Open the Facebook application and tap the Menu button (☰) at the top right
With the mobile application you can only change the contact and recovery email address, while you cannot change the email account generated by Facebook. In the latter case, read the previous section to find out how.
Step 2. Scroll down and tap "Settings and Privacy", then "Settings"
Step 3. Tap "Personal Settings", then "Email"
Step 4. Tap "Add Email Address" and enter the one you want to use
Step 5. Enter your password and tap "Add Email"
Step 6. Open the verification message sent to the new email account
Step 7. Follow the link to confirm your email account
It will then become the primary contact and recovery address associated with your account.
