I also use Keepass, with a complex master password that I've memorized. I keep the file in my Nextcloud instance so that it's synced between my two Android devices and four Linux machines.

Similar setup, MacPass (a new implementation of keepass for the mac), ChromePass for autologins, and KeePass2Android on my phone. Works well, not perfect but enough for what I want.

This is what I use, but also use Syncthing to sync it between my laptop, phone, and raspberry pi and fileserver (for backup).

It works very well from my experience.

I use Keepass also, more specifically https://www.keepassx.org
