The RTCIceParameters dictionary specifies the username fragment and password assigned to an ICE session. During ICE negotiation, each peer's username fragment and password are recorded in an RTCIceParameters object, which can be obtained from the RTCIceTransport by calling its getLocalParameters() or getRemoteParameters() method, depending on which end interests you.


A DOMString specifying the value of the ICE session's username fragment field, ufrag.
A DOMString specifying the session's password string.

Usage notes

The username fragment and password uniquely identify the remote peer for the duration of the ICE session, and are used to both ensure security and to avoid crosstalk across multiple ongoing ICE sessions. See RTCIceCandidate.usernameFragment for further information.
