export 2fa

Is your feature request related to a problem? Please describe.
A clear and concise description of what the problem is.
I've been looking for an easier solution for filling 2fa codes, because Magikeyboard is frankly quite jank and not user friendly, so I decided to try a different app for 2fa codes. Unfortunately there's a lot of friction moving apps, because there's no export function for 2fa secrets.

It would be extremely useful if there was an export function to allow us to import the 2fa stored in Keepass to a different app (possibly by QR code?)

Describe alternatives you've considered

Inputting them manually is possible, but quite a pain, especially if you have a lot of apps that have 2fa.

No files, tests, or entry points are named; start by identifying where KeepassDX stores 2FA secrets and how Android app data can be shared. Done should be defined as a reviewed export format and an importable result for another 2FA app, with security and QR behavior agreed.
