Adding mail when we cant acess fb

You're referring to the feature of adding a mail address when you can't access Facebook due to various reasons. This feature is called "Alternate Email" or "Recovery Email" and it's a security measure that allows you to add an email address that can be used to recover your Facebook account if you're unable to access it.

Here's how to add an alternate email address on Facebook:

Once you've added an alternate email address, you can use it to recover your Facebook account if you're unable to access it due to various reasons such as:

• Forgotten password
