I've been using
https://1password.com/ for many years and quite happy with it. The main feature I find useful is it works on all my devices with a native app on each platform and it synchronises my passwords for me in a secure and encrypted way (the 1password developers never have access to your passwords due to the local encryption it uses before synchronising things).
So whether I'm using it on my PC, Mac or iPhone it's always ready with all my passwords already synchronised.
There are many alternatives, some free and some paid but I've only used 1Password myself.
