Proton is also the ONLY passkey provider that I've seen allowing you to store, share, and export passkeys just like you can with passwords!
1Password has had this for several months.
As others have mentioned, Bitwarden also has this. This really feels like an ad.
It was a recurring bit on John Oliver’s show. Should be turned into a book though.
Microsoft Authenticator does more than just TOTP codes. It allows IT departments to push https://learn.microsoft.com/en-us/mem/intune/apps/app-management instead of MDM on personal devices.
For apps like Outlook, Teams, and OneNote the app data can be wiped without wiping the whole phone.
For any of that to work, Microsoft Authenticator has to be used as the “broker” for that authentication.
Looks like they are just rolling out support for Android 14 and up.
