"Forgot password" links usually send the user to a url with a single_access_token hash at the end. There, you identify the user and let them update their password to their liking. This way you do not irritate users who don't want you to have access to their passwords which they might also use for their bank accounts and social connection pages.
Another way is to set the password to a hash such as
user.password= @new_pass #MD5.digest(Time.now)[0..7]
# set password_confirmation and reset password token for "change password on login", too, if neccessary
user.save
In User model after_update :email_password_if_password_changed if password field has changed, you can email their password using activemailer.
