This is a **community-driven** list of known passkey provider AAGUIDs to assist with naming passkeys in end user passkey management interaces (e.g. account settings). **It is not intended to be used for any other purpose** and **_could go away at any time_**.
This does not replace [FIDO's Metadata Service (MDS)](https://fidoalliance.org/metadata/), which should continue to be used for all authoritative security details about FIDO authenticators. Some AAGUIDs in this list may not appear in FIDO MDS.
