Ofcouse one should backup their stuff, including whats inside Bitwarden. Here is how I do it:
- Export the Bitwarden vault to EFS encrypted folder
- Log in to KeePass XC which is inside Veracrypt container
- Import the exported vault to Keepass XC database (put a date to it) as a new folder
- Save & exit Keepass XC & Veracrypt
- Wipe the exported Bitwarden vault from EFS encrypted folder
- Every now and then (like every couple months), copy th Veracrypt container to external hdd1 (in a folder with a date), keeping multiple Veracrypt container backups there.
- Every now and then (like 1-2 per year), put the hdd1 to storage (outside my home) and pickup the hdd2 from storage and start using it for backups…and vice versa.
Oh, why do I use both Keepass XC & Bitwarden to store my passwords? Because I need to store other data too and storing 2FA:s inside the password manager you use daily is a serious security issue, nullifying the protection that 2FA provide and are for…please check this thread about the subject
