DOMString containing the username fragment (usually referred to in shorthand as "ufrag" or "ice-ufrag") that, along with the ICE password ("ice-pwd"), uniquely identifies a single ongoing ICE interaction. The string may be up to 256 characters long, and has no default value.
At least 24 bits of the text in the
ufrag are required to be randomly selected by the ICE layer at the beginning of the ICE session. The specifics for which bits are random and what the remainder of the
ufrag text are are left up to the browser implementation to decide. For example, a browser might choose to always use a 24-character
ufrag in which bit 4 of each character is randomly selected between 0 and 1. Another example: it might take a user-defined string and append three 8-bit random bytes to the end. Or perhaps every character is entirely random.
