I would like to create URL’s that, if the user clicks, log them in automatically without having to supply a username and or password.
Anyone know how to accomplish this in Devise with Rails 3?
Preferrable the URL’s that are generated to login a user are as short as possible.
If you are using devise you can use token authenticatable.
