I didn't realize login was allowed with aliases until I saw this suggestion. This is scary. I don't see any benefit to the user to be able to login with say 5 different email addresses for the same account. If they are the real account owner, they should have no issue securely storing the credentials for the main/login account (whether this is the original one, or something chosen as others have suggested). Allowing login from any alias just increases the likelihood of an unauthorized party gaining access.
