I admit that I didn't look closer to brave sync and pwd management, because I somehow don't trust them (or even chromium).

On the other hand bitwarden code was internally audited in our company and I do trust our guys (who I know personally) and theirs skills.

Anyways, the seed phrases (and other really sensitive shit) I keep in a keepass db in an always offline VM and usb sticks (even LUKS protected LOL).

I don't have anything physical (like steel engraved or paper) because hackers are not my concern, police raid is.
