Keychain and multiple different passwords; no sync
I found about 14 different entries in my "passwords" dialog box of Safari Preferences, all for the same userID. Several were for id.apple.com, several for iforgot.apple.com, several for daw.apple.com, and several others for various other apple.com subdomains. There were several different passwords for the exact same subdomain, and no indication as to which one was the most recent. So it does no good to look it up!
This is a real PIA if when logging in, 3 authentications show up as "from this site" all with different passwords. I thought that when you changed a password, that would remove ALL the other password entries for that subdomain in the "Passwords" dialog box in Safari Preferences, but apparently not.
And getting these to sync across to the phone is another hassle. They just don't sync, even though I have iCloud Keychain turned on anywhere I can find it. So I wind up with totally blank userID and password fields on the phone for a site that fills in perfectly on the Mac. And of course, I don't "know" the password because that's what iCloud Keychain is supposed to be for! And I can't "look it up" because the Mac is at home and I'm not.
Finally, does anyone know why logging into iCloud isn't done by the Keychain? And iTunes Store? Neither of these EVER fills in the password from my Keychain. And did anyone ever try to enter those xxx-yyy-zzz-www type passwords on a phone? You'll be admitted to the nuthouse after 2 or 3 times doing that, shifting between upper case, lower case, the hyphen, and the numbers. Arghhhhhh...
Why doesn't this work? It's a good idea.
