I use traditional KeePass. I find it less bloated than it’s forks. I keep my database and keys in a Tresorit folder. I’ll eventually self host them, but I’ve been too busy. I have KeePassium on my iPhone. It’s free version (2 databases) works fine for me. Strongbox is the most popular option. I just didn’t love it. And I’m experimenting with IOSKeePass, which is a fork of the old MiniKeePass which was great, but was deprecated.

I’ve also played with Bitwarden. It’s an incredible service. I recommend it to anyone that seems hesitant to deal with the KeePass difficulty level. The free tier will give you everything you need and more. But for a whopping $10 a year, you get a bunch of extras including support.

KeepassXC has worked pretty well for me. You'll need something like syncthing to synchronise the database across devices though!

Oh just to add, each OS probably has several implementations of Keepass, you'll have to search for one for your respective platform. KeePassXC just happens to be the one I use on Linux and then I've got KeePassDX for my Android devices.

Bitwarden, run your own server mode
