It’s just a wrapper on top of Docker. You can import your own yaml files when you create your setup.

Ah! Misread your comment in that case.

So… I use a physical passkey as a second factor on top of username and password on all three of my Synology-boxes. I have TOTP as backup in case I should lose my passkey.

Anyways - synology has no clue about my phone number, so I’m not sure I agree with your sentiment that it’s a requirement.

You might also want to check that your controller really supports hot-swapping. Not all do.
