Support certificate-based authentication

[wrestle1]

Passing and/or storing unencrypted passwords in becoming more and more unacceptable. It would be nice if the application supported certificate based authentication. An alternative would be to have a callback that can retrieve a password from a secure source.

a certificate won't solve the security risk , it is the same role as a password but adding on top a trusted authority and an expiration date. I will have to think more on the issue to come to some solutions

May be something like a 2 Step Authentification to retrieve those password by SSL
