This standing as a plaque
Firebase Authentication currently holds a silver deskmark here — Rank 4 of 9 · Auth Identity. Anyone may show it. There is nothing to apply for, nothing to pay, and displaying it changes no score: the standing comes from the published algorithm, which never reads commission data. We never ask anyone to show it, and its link carries rel="nofollow".
The image is drawn from our live data, so it follows the standing rather than freezing it: if Firebase Authentication moves up or down a tier, the plaque on your own site says so at our next publish. Nothing is tracked beyond the ordinary web-server log that records any image request.
