Vanguard on Web supports Passkeys for 2fa, but the iOS app seems to only support text-sms 2fa. Robinhood supports passkey login on iOS app but doesn’t seem to require it for 2fa, email+password succeeds with no further prompts. But on Web it doesn’t support passkey at all, and email+password requires you to confirm auth via an in-app notification. Both Robinhood and Vanguard support FaceID biometric auth for their apps. All I want is passkey auth everywhere and/or email+password with options for passkey and TOTP for 2fa. Ugh.
