+1 for this work. If you are one of those that think, as I did 20 years ago, that password authentication is dying and practical replacements are just around the corner, do not support this document. Otherwise, please do.
Asymmetric or augmented PAKE (aPAKE) protocols provide secure password authentication in the common client-server case (where the server stores a one-way mapping of the password) without relying on PKI - except during user/password registration. Passwords remain secure regardless of which middleboxes or endpoints spy into your decrypted TLS streams. The server never sees the password, not even during password registration. To see real deployment of such protocols, they need to be integrated with TLS which is what Barnes's draft facilitates. Not only this improve significantly the protection of passwords and password authentication, but aPAKE protocols also provide an hedge against PKI failures by enabling mutual client-server authentication without relying on regular server certificates.
