I’m using Bitwarden
2023.12.1 2024.1.0 (non AppStore version) on macOS Sonoma 14.2.1. I’ve started cautiously using Passkeys recently for some sites and it’s working pretty well.
Yesterday I tried to set up Passwordless auth to my Microsoft M365 tenant using a Passkey. I did this from the standard My Sign-Ins page. I wasn’t able to complete it, instead getting an error message at the final step from Microsoft:
There’s a Passkey showing up (dimmed out) for that login in Bitwarden now, but I can’t use it.
I found this page which indicates that Passkeys aren’t (yet) supported for M365 logins. It says “Microsoft Entra ID currently supports only hardware FIDO2 keys and doesn’t support passkeys for any platform.”
Can anyone shed any light on whether this is possible, or if it’s “coming soon” or never?
