I now use the following in self custody on my own hardware:

- Vaultwarden with encrypted backups on a USB Stick

- Nextcloud

- Bitbox Hardware Wallet with Steel Wallet as Backup

- Bitcoin and Lightning Node

- lightning address using my own domain

- TOTP for 2FA with encrypted backups inside my Nextcloud (I am switching to a hardware key later if possible); without saving the password in my Vaultwarden of course

Anything missing? I am maxing out self custody and security at the moment.
