I like being able to log-in on proton services on a browser using a QR code scanned on my phone by the mail app. It doesn't require entering my password and going through 2FA each time.

However, it is seen as a recovery method at the moment, and thus hidden behind multiple menus (on the browser and on the Android mail app).

Is there a reason to not have this method as a standard way of log-in, with the feature available in the higher level menus? It would be even more convenient to have it as a quick action on the mail app for example.
