QR code to connect mobile apps is very hidden

[sedrubal]

Is your feature request related to a problem? Please describe.
When you want to connect the Nextcloud Android App to your account, the app shows a button to scan a QR code. However, it does not explain where I can find this QR code in the nextcloud web interface and the QR code is very hidden in the nextcloud web interface.

Describe the solution you'd like
I want 2 things:

• the app should explain where I can find the QR code
• the QR code should be easily accessible in the web interface. I expect it to be under "Mobile & Desktop" and "Security". As the QR code encodes a newly generated App password, there could be a button named "connect Nextcloud Android / iOS app using QR code", which generates a QR code and displays it.

Describe alternatives you've considered
My solution was to google where I can find this QR code.

This should probably be promoted into a separate entry in the main menu (same level as "Personal Settings" and "Administrative Settings"), or even into its own separate button in the same row as the user's avatar.

Even going into settings is already too much hassle which reduces the usability to near-zero.

I can only agree after looking for this feature.
I'd guess that 90%+ of all users trying to connect the App will end up searching online which is definitely not a sign of good UI/UX.
