-# MSC2078 - Sending Password Reset Emails via the Homeserver
+# MSC2078 - Sending Third-Party Request Tokens via the Homeserver
 
 This MSC proposes removing the current requirement of the identity server to
-send password reset tokens, and allows homeservers to implement the
-functionality instead. The intention is to put less trust in the identity
-server which is currently one of the most centralised components of Matrix. As
-it stands, an attacker in control of a identity server can reset a user's
-password if the identity server is considered trusted by that homeserver, and
-the user has registered at least one third-party identifier (3PID). This is due
-to the identity server currently handling the job of confirming the user's
-control of that identity.

+SMS. The latter is what this proposal mainly focuses on, but be aware that it
