If you're already using Nord for VPN, then that's probably a good enough option. The hassle will be if you leave Nord and need to transfer your passwords to a new manager.
I am using Lastpass right now, but recently they changed things to make it less useful. I'm probably going to change to Keepass for my requirements, but it's a bit more stuffing around to manage it properly and I haven't summoned the will to get it done yet.
