In-app 2 factor authentication

[ghost]

For example, if a person was to store their Google account login details on SealNote, why not implement an extra field for those using 2FA for their account? It would allow people to delete the old, obsolete and insecure Google authenticator app (for those who still use that), plus it shouldn't be too hard to implement as there is plenty of freely available code regarding 2FA out there. As for the barcode scanner, those who use 2FA have a barcode scanner installed already.

The SafeInCloud app has a working solution which is simple and effective.
Since the app is paid only, I took a video of the layout and process: https://www.youtube.com/watch?v=8jlOipv7ayk
