.auth Domain Names

Prelaunch / not delegated

.auth is a proposed generic top-level domain associated with authentication and trust. Publicly announced information identifies Link Freedom Group as the applicant associated with.auth, but the string is not listed in the IANA root zone as a delegated domain. That makes it a prelaunch extension rather than an active live TLD at present. (lfg.link)
