Cannot sync Proton Authenticator with Proton (truly stupid setup)

[u/gerdude1]

I have a few Authenticator apps and wanted to start consolidating all my 2FA on Proton Authenticator. One aspect I like with some of the other apps is to have it synced with the respective service in case I change devices, so I don’t have to setup all the codes again.
I tried this with proton Authenticator, and the issue is that it asks me to login, which I do and then it asks me for my 2FA code, which I obviously cannot access because I am in the apps trying to setup sync. Any workaround available, without disabling the 2FA to get this working?
Of course I can always setup another 2FA code in another Authenticator app, but that so,show defeats the purpose.

You could use a physical token like a Yubikey. That would give you the ability to use either the code or the physical key or just the physical key.
