1Password is by far the best password manager out there. None of the other apps can stand up to it in terms of app and browser extension usability, reliability, and security. The Watchtower feature is amazing and helped me to go through and update all of my roughly 100+ weak or reused passwords to be cryptographically secure randomly generated passwords.

I also like the many different options for categorization; I run a home lab server so I use 1Password to store things like IP addresses of services I'm running, IP/MAC address whitelists, SSH keys, etc.

They also have secure notes, which I use to store a couple license keys for some software I've purchased.
