Many lost password workflows usually result in a page which is reached by a temporary link emailed to the user. This link then takes them to a page that asks for a new password.
Upon entering the new password should a user be forced to logon manually, or should the password reset page authenticate the user automatically which would reduce the number of steps and thus complexity of the process for the end user?
I often encounter password reset pages that make me reset my password and then login which feels like I'm logging in twice for no good reason.
