Please add an option in Proton Authenticator to log in using a QR code and a temporary (one-time) password, similar to Yandex and their Yandex.Key.

It’s very convenient: on the browser login page, there’s an option to log in via QR code. If you scan it with the authenticator app or even the camera, you are logged in automatically. If the authenticator isn’t installed on the phone, the link from the QR code is sent to the service’s app (e.g., email app), which then sends a notification like “Do you want to log in?” — this is how Yandex and Google do it, and it’s very handy.

The temporary password is also useful because I don’t need to enter my username + password and then a 2FA code. It’s very secure, especially when logging in on a shared computer: I can either authorize via QR code or use a one-time password. This way, I don’t compromise my main email password.

Please check how Yandex implements this with Yandex.Key. Proton really needs this type of login!
