I do not need to remind you of the importance of good passwords, certainly in this age of put-everything-in-the-cloud you need strong passwords and different ones for each service. There are a lot of utilities to help you, but one very handy one is hidden in the OS X change password dialog: When you click ‘Users & Groups’ in ‘System Preferences’, click a user and then click on ‘change password’, the following dialog appears. Click the key icon and you get some help choosing a password. You can get categories like ‘memorable’ or ‘numbers only’, you can choose the length and your Mac will even tell you if it is strong enough. Of course you do not need to use it for your OS X user account only… copy paste to wherever.
But don’t forget you have to remember your password ! The next iteration of Os X (‘Maverick’) will have a password store for Safari, but I store them in my favourite brain Evernote. Not in clear text of course.. Evernote allows you to encrypt part of your notes. Just paste text in a note, highlight it and choose ‘Encrypt selected text’ from the edit menu. Choose a pass phrase and… presto !
