Avoiding the login & password authentication is a desirable feature (see http://www.mozilla.org/en-US/persona/) but a user authentication is still required at some point : unlock the secret key, use browser on public access devices, etc.
Since typing a user identification and password is not convenient with touch screen devices, we should obviously use method adapted to such types of interface. A combination of taps and slides on a changing interactive pattern could do the job. The service needs only to allow using both methods to authenticate.
A javascript widget with a commonly accepted method would be great to have.
Sending credential by mail and making their use implicit from a particular browser seems unsafe.
