How do I sync keychain on multiple macs?

Hi

There are a lot of forums on this subject, but are specifically about Apple removing Keychain sync with iCloud. I cannot find any solution as to how to do it now they removed this option.

I have installed Keychain2Go but it just synced right away to "somewhere". I guess it's their servers. So I am concerned about that as I don't know this company.

So is Keychain2Go the only solution to sync Keychains now? I cannot find any other solution.

Thanks
