Temp mail for Facebook
Facebook accounts tend to collect years of photos, messages, and logins to other sites. A temporary email is a risky foundation for that.
How Facebook uses your email
Facebook can use your email to confirm the account, alert you to logins from new devices, and help you recover the account. Many other apps also let you sign in with Facebook, so losing the Facebook account can mean losing those too.
Facebook’s own rules ask people to use their real identity and not create fake accounts. A temporary address doesn’t change who you are, but if it is the only contact on the account, you can’t prove the account is yours once the inbox is gone.
What happens after 24 hours
Our inboxes end 24 hours after they are created. Shortly after that, the address is deleted and rejects all mail, permanently. A login alert, a password reset, or a “confirm it’s you” check sent there will never reach you.
Cutting Facebook email without losing the account
- Turn off the email notifications you don’t want in Facebook’s notification settings.
- Use an email alias that forwards to your real inbox, so you can switch it off if it gets spam.
- Use a filter in your email app to send Facebook’s notifications to a separate folder.
When a temporary address is fine
For things around Facebook rather than the account itself: a contest run by a Facebook page that asks for an email, a download linked from an ad, or a shop you found through Facebook and haven’t decided to trust yet.
