Where to store your Microsoft 365 passkey?

Microsoft 365 (Entra ID) has supported passkeys for a long time now. From auto-registered passkeys like Windows Hello to synced passkeys.

I’ve created this tool to quickly see the current capabilities, to use for conversations with colleagues or customers. I try to keep the page current as features will be added or change. I will also expand the subpages with relevant context, risk considerations, dependencies, limitations, user experience, and caveats.

The tool can be found here: https://passkey.janbakker.tech/

It also has two handy links to the Passkeys Authenticator AAGUID Explorer and the nudge simulator I’ve built.

Stay safe!
