How common (or uncommon) is using full email address for email login?
- by somecallmemike
I was hoping you fine folks could comment on your experiences with using a full email address as a login name for an email service vs. using the username (everything before the @domain.tld).
I ask because I have inherited a legacy email system in which usernames are completely unique, and users can log in via that username (to other services besides email as well) and I do not want to ask tens of thousands of users to have to update their email settings to support virtual domain hosting without good reason.
