Summary

The Blockstack browser does not use traditional user sessions. Rather, each user session is entirely decentralized -- no remote server "manages" a session. Because of this, two user sessions in two different browsers are completely independent. One cannot change the password of the other.

Because of this, we do not believe that "session not expiring after password change" is a bug or a vulnerability.
