How to set up FIDO2 on your mobile device
FIDO2 is an open authentication standard that is used in hardware security keys, passkeys, and other cryptographic credentials. You can now use a security key for your two-factor authentication (2FA) to get into Proton Pass in place of a time-based one-time code. This makes 2FA even easier as all you need to do is tap or plug the key to your device to be authenticated.

Set up your security key
You can use a security key to authenticate your identity on Proton Pass. This key is either a USB or NFC device that you can tap or plug into your device to use as a passwordless identity authenticator. Please note that you’ll need to have 2FA enabled on your device and a 2FA authenticator app installed to set up your security key.
