Sign in with Passkeys aka FIDO multidevice credentials.
At the moment 2FA sign in at proton is possible using a security key. The new fido passkeys protocol works exactly the same. Yesterday I created such a passkey in my iCloud account for 2fa signing in at Proton. Imho the sign flow at Proton using a 2FA key seems a little outdated.
To avoid long discussions: Using the new fido sign flow users can choose between a software generated passkey where the private key is stored in a password manager. Or with a physical security key. In which such a key is always better, but not everyone has such a key.

Yes! Passkeys are the future. We would like to see this implemented.
