iCloud Keychain is apparently the way ahead, but even Apple has a great deal more work to do before that’s feasible. A look at what’s needed.
Keychain Access
Multiple requests for a keychain password, login password mismatch, broken keychains, expired certificates, and using the Data Protection keychain.
macOS has two types of keychain, and its tools for working with them, Keychain Access and the command tool security, only work fully with one type.
Solving repeated requests for passwords, telling the genuine from the bogus, how passwords can become mismatched, and more.
What are keychains? What do they store? Which are essential on Macs, and why do you get prompted to enter your password for access to them? How secure are they in iCloud?
What to do when your browser complains that a website you want to visit has a problem with its certificate security.

So you want to try a 3rd party password manager, but use Safari as your browser. How do you import its stash of passwords, or keep an independent record of them?
Why do we keep having problems with security certificates when they’re just supposed to work? A look at what they do, and they work.
Keychains contain some of our most important and precious data, and are often shared with iOS devices using iCloud. How can you back them up then?
