Is it possible to use passkeys for sign-in-2FA, as described here? <https://support.kraken.com/hc/en-us/articles/360000911823-How-does-two-factor-authentication-2FA-for-sign-in-work->

Sure. Take a look at <https://www.ory.sh/docs/kratos/self-hosted/mfa#webauthn>

thank you, it does not work for passkeys, though (which are aal1-only in kratos)

passkeys subsume password+OTP, they are considered to be 2FA: <https://www.binance.com/en/support/faq/how-to-create-a-passkey-for-my-binance-account-2aec8fe0437242f2a5fbef9cdb71d4c2>
would it be possible to configure passkeys as aal2, just like with webauthn?
