I want to second keepass2 here. I'm using it for a years and the database format is uncoupled from the client. There are many different clients (I use the official one for windows and Keepass2android, but there are also linux and macOS clients available) and addons that make it better. E.g. "kee" previously "keefox" automatically fills in passwords to webpages and saves new logins, if you want to and use Firefox (which is definitely worth a try after the big upgrade last year if you are currently in Chrome). The database file is strongly encrypted and you can lock it with a keyfile and a password. It's easily synced with Google Drive or Dropbox. Keepass2Android even provides direct connection with a Dropbox or Google Drive database file. Conflicts are easily resolvable in case an update didn't get pushed until you change something at another device. I sync the 1024bit keyfile using usb sticks (only needed when setting up new devices) and a long password (the only one I have to remember). You can even import passwords from your local firefox password manager and from 1password (though import from 1password seems to run through unencrypted csv files. And you get all that for free.
