Login Name Password question with 3 macs in Hardware Stuff Posted August 3, 2011 What John said. As long as your MobileMe acct is set up properly in system preferences you're good to go. But, like Apple Geek pointed out, Keychains will cease to be synced when MobileMe ceases in June of 2012. At that time you might want to consider something like 1 password. OR you could develop a password scheme for yourself that enables you to easily remember all your passwords. What I mean is this. Come up with a series of 4 or 5 passwords. Make them all complex ( upper and lower case letters numbers and symbols ) and make sure they are all unrelated ( if you use a former pet's name in one password, don't use another pet's name in another password, etc ) but compose them so that YOU can memorize all of them easily. The idea is to NOT show a patern among these passwords. Then, simply devise a rotation for these passwords amongst the various programs and sites you use. Every six months, rotate the passwords so that sites get their passwords changed frequently. Actually, using a system like this protects you more that having the same passwords at the same site for years ... even if you have a different password for every site.
