Consider pass (passwordstore.org) as password manager.
https://www.passwordstore.org/ is a DYI password manager solution, which is essentially GPG+GIT. This is not the easiest to set-up when compared to commercial products, but at the end it's as secure as the remote git repository of your choice, and the device security on which you hold your private GPG keys. Free and open source, plenty of apps for iOS/Android/Browser integrations.
