Question

I am looking into moving my authentication in a CakePHP app to Rails Devise. However, our site uses usernames as a unique identifier rather than email, as often families use the same email address on multiple accounts.

By default it looks like Devise uses email as a unique identifier – is it possible to have multiple accounts with the same email address when using Devise?

Answer 1

Set

config.authentication_keys = [ :username ]

in your device.rb. You may also use the following settings to make login more solid

config.case_insensitive_keys = [ :username ]
config.strip_whitespace_keys = [ :username ]
