Description

### Your use case

#### What would you like to do?
I want to be able to use my telephone number with more than 1 account.

#### Why would you like to do it?
I change accounts occasionally because I am unable to replace the username of my account. Consequently, migration is necessary. However, I want to retain my ease of access to my previous accounts and backup methods of access, because 2FA is enabled for all of them.

#### How would you like to achieve it?
Allow usage of a telephone number with more than 1 account.

### Have you considered any alternatives?
Yes. 0 exist.

### Additional context

Per https://github.com/vector-im/element-meta/issues/893#issuecomment-1378554941, this has been reported here.
