Authentication - Do you use email address instead of user name?

It is easier for users to remember their frequently accessed email address more
so than one of their many user names. For this reason, it is best to use email address
instead of user name for the sign in page.
"I do recommend letting users enter their email address instead of a user ID: It's guaranteed to be unique and it is easy to remember."
Jakob Nielsen, Ph.D. and Principal at Nielsen Norman Group
- Figure: Bad example - users have to remember which username applies to this particular website
- Figure: Good example - users will always remember their primary email address
