Get a good, randomish password from your Mac
The password assistant in OSX is the work of a genius. Seriously, Apple put the smart guy to work on this.
If you ever need a strong password for something, open Keychain Access (cmd+space, type k e y c then enter) and click the plus sign to add a new key. Next to the password field, there is a key icon, which you click to open the Password Assistant.
Play with the password type and length. Pretty sweet, right? Now here’s the genius: click the Suggestion dropdown. It doesn’t just give you one suggestion, it lets you choose from several.
By the way, the Memorable option is a little too predicatable for my taste. You don’t have to use dictionary words to create memorable passwords.
