What will happen to the account when mail disappears?

Question

Email

Let's say an account has been created on twitter.
A temporary mail service was used as an email (for example, 10 minute mail)
What will happen to a Twitter account after the disappearance of the temporary email on which the account was created?

Answer 1

Most likely nothing, but you will lose the ability to recover your password and other mail-related goodies.

Answer 2

Nothing will happen, you just won’t be able to get the page back if you forget the password from it.
Or anyone can access it knowing the mail (depending on the service).

Answer 3

You just need to remember the password and that's it. Otherwise, you will not get access to your twitter account.
