An email address is not an immutable property of a user so I find a username is a better way to identify a user.

  That's what database-level user IDs are for. Don't push your technical requirements onto the user when it's not needed.

    If someone uses their work email as a username, they loose their ID if they leave the job. Even worse, the employer may give the same email address to someone else.

      If you're allowing emails as a credential reset mechanism, you've already got that problem.

  Neither is username; people have very good reasons to want to change their names
