I have used the excellent 1Password software for quite a while. The Mojave version is excellent, although I don’t like the fact that it no longer automatically logs in for you. The 1Password people say that is a security risk, so they have disabled auto-login. One thing that bugs me about 1Password is when it wants to save passwords on websites where I prefer it not too. Not a problem though, this article explains how to de-activate saving for specific websites.
