You can use KeePass, but you’ll have to figure out a way to have your password vault available on other devices (can do it by using any cloud shares, i.e. GDrive). This way you’ll be in charge of almost every aspect of your passwords. But you’ll have to take care of backups and keep everything in sync.
I tried using free tier NextDNS on a network with 2 Samsung TVs hooked up and hit the threshold of 300k requests within a week. It’s mad how much data Samsung is collecting from their smart devices. Even when not using any features, the TV may stay with a screensaver and still send lots of data.
