I remember it always being behind keepass, and when keepassxc came out immediately started using that, but I'm still sad to see this stopped.
Also, KeyChain is not a real password manager, lacking many fields and features. It’s not a substitute for a fully fledged password manager.
I don’t trust and don’t use it for serious passwords.
Take a look at KeepassXC.
Keepassxc is an advanced password manager, and ahead in terms of features and usability.
