Why don’t people use their own TOTP provider, like KeepassXC/Strongbox, storing the DB in an encrypted manner on a cloud of their choice.

Then use across multiple devices.

It took time for this to sync in, so maybe that’s why so many others do not see that there is really no need to have a third party involved in this pattern?

It's fairly easy to make your own TOTP provider.

I wrote a simple CLI TOTP utility that works using an AES encrypted lookup table of secrets.

I piggybacked access to this off an unrelated web site and it is now readily available from any device if you have the decrypt key and know the URL.
