OS X Mountain Lion: Tips for creating secure passwords
Create unique, secure passwords
- Choose a password with eight characters or more and a mix of different character types.
- Don’t use names, words found in a dictionary, phone numbers, dates, or simple combinations of these.
- Avoid using a pattern of keyboard characters, such as diagonal lines of keyboard keys (for example, njimko).
- Use a sequence of random characters. Include a mix of upper- and lowercase letters, numbers, punctuation marks, and (if the site or item allows it) characters typed while holding down the Option key.
- While defining a password, use the Password Assistant to see how secure your password is. To open the Password Assistant, click the Key button next to the Password field or the New Password field.
Create easy-to-remember passwords
Start with a phrase, verse, or line from a song. Omit some letters, and transform others into numbers or punctuation marks that resemble the original character. You might want to insert additional punctuation and numbers too.
For example, the phrase “You will be welcomed” could be turned into “UW1llBvv3lc0meD;”.
And, of course, don’t use this password—everyone who reads this example will know it!
