I have said time and time again, keep a copy of the QR code (or the text encoded within) before adding it to an authenticator app. You may find out too late that you cannot recover the keys. You can do this by simply taking a photo or screenshot of the QR code and storing it in a safe place.

Even better, avoid any MFA mechanism that relies on short codes with low entropy. Instead you could use U2F which uses a hardware token in which the key material is designed to be extremely difficult to extract, and requires physical access to the device to even attempt.

This is the nice thing about keeping it in Keepass XC. The seed is saved as an attribute in the database, you can easily add it to another app if needed.
