frozen_nick

Frozen Nick

This plugin stops users from changing display name if JWT auth is used and name is provided in token context.

This is useful in a setup where user identity is established in another app and passed to Jitsi via JWT. Allowing users to change display name from a client app weakens the link between Jitsi user and in-app user identity.
