# vault.session_linked

> An open vault session got its user: a new enrollment finished, or a returning user signed in with their passkey.

An open vault session got its user: a new enrollment finished, or a returning user signed in with their passkey. Store `user_id`. A connected session already named its user, so it does not fire this event.
