Passkeys do not work with Microsoft 365

Hey leonardder!

On Firefox, 1Password reported an unknown error before it was able to save the actual passkey.

This is a known issue that we've been able to reproduce. I'll add your instance of the issue to the ticket we're using to track the behavior. Hopefully our developers can come up with a fix for it in the future.

As for saving passkeys for work and school accounts, that appears to be an issue on the Microsoft side of things. I recommend reporting it to Microsoft: https://support.microsoft.com/en-us/contactus

Passkeys are quite new, so hopefully we'll see lots of improvements from our side and from other companies as they implement passkey support on their websites. Please let us know if you have any other questions or need more help!

I can still reproduce the issue with Microsoft 365 with version 2.12.2 of the Firefox extension.

I can reproduce both, i.e. I am able to add a Passkey to my personal Microsoft account in Edge. On Firefox, 1Password reported an unknown error before it was able to save the actual passkey. For work accounts, I also get stuck in the naming step.

There are 2 kind of accounts from Microsoft:
- Microsoft accounts (personal ones : like with Outlook.com, Hotmail.com, Xbox etc.)
- Work or School accounts (professional ones : Office 365, Microsoft 365, Azure).

I have tested both:
- Microsoft accounts:
works when you add a security key
- Work or School accounts:
does not yet works
- Behavior observed: FIDO2 Security Key has to be activated by the tenant Admin

• on the page: https://mysignins.microsoft.com/security-info, you can add a new method (choose Security Key)

• Choose USB or NFC

• 1Password extension will popup letting you choose the account to use for the passkey.

• However, on the naming step (Microsoft page): same error as in this post.

It seems Microsoft doesn't handle something.

Contrary to what the passkey key directory site by 1Password says, Microsoft don’t support them yet
