In Canada the title "Engineer" is protected by law. One must have an engineering degree from an accredited university in order to use the title. It's fairly strictly enforced.
I use BitWarden and run my own vaults. Pretty easy to set up using docker on a Linux machine.
I've had some trouble with the BitWarden anrdoid app not wanting to help fill in login information, but I put that down to user error - it's close enough I just can't be bothered to dig deeper.
