> And what happens when I need to login to a device I don’t own, or don’t have/want my personal password manager on? For that there's CTAP2/WebAuthn: https://fidoalliance.org/fido2-2/fido2-web-authentication-webauthn/ https://fidoalliance.org/fido2-2/fido2-web-authentication-we... "The other component of FIDO2, Client to Authenticator Protocol (CTAP), is complementary to WebAuthn. It enables an external authenticator, such as a security key or a mobile phone, to work with browsers that support WebAuthn, and also to serve as an authenticator to desktop applications and web services." https://techcommunity.microsoft.com/t5/security-compliance-and-identity/all-about-fido2-ctap2-and-webauthn/ba-p/288910 https://techcommunity.microsoft.com/t5/security-compliance-a... "CTAP2 and WebAuthn define an abstraction layer that creates an ecosystem for strongly authenticated credentials. Any interoperable client (such as a native app or browser) running on a given “client device” can use a standardized method to interact with any interoperable authenticator – which could mean a platform authenticator that is built into the client device or a roaming authenticator that is connected to the client device through USB, BLE, or NFC." And for the multiple person needing access to an account thing, password managers that store the passkeys allow sharing: https://support.apple.com/guide/iphone/share-passkeys-passwords-securely-airdrop-iph0dd1796bb/ios https://support.apple.com/guide/iphone/share-passkeys-passwo... Or alternatively, you just add a passkey for each of you in your own password manager to the accounts that you both need access to.
