If a hacker can get into your iCloud account, they can get into and control every Mac, iPhone, iPad or iPod touch you own — it is just that simple. You need a strong password not only for iCloud but every account, service and device you use, and Apple’s got your back.
Yes, OS X Mountain Lion includes a secure password generator. Specifically, the password generation is integrated into Apple’s existing password manager, Keychain Access, and it is super easy to use.
Find and use the Keychain Access password generator:
• Open the Keychain Access app (Finder > Applications > Utilities)
— Or just search for using Spotlight
• If necessary click the lock in the upper left hand corner and enter your system password to unlock the app
1.) Click the “+”
2.) In the resulting window, Click the “Key” button
And, there you have it — fast, easy and secure passwords at the ready whenever you need a new one. Just copy and paste, or work with your new secure password right inside Keychain Access.
