What is the correct way of getting a membership provider where user id = email?

Question

I want to implement membership where email is used as the user id. Is there a ready-made provider for this, or do I have to write my own one? Or should I just make do with the 'default' one?

Answer 1

You can use the default Sql provider stack without modification.

Simply use an email address as UserName (or login id) when creating the user.

Please know that UserId is an interal surrogate key.

I think that you are conflating UserName (or login id), which is a string and can contain an email address, with the UserId column in the membership database, which is a Guid and should not be changed.
