As a network and security professional, my recommendation is for users to develop their own personal set of sayings or sentances and then use the first letter of each word in that sentance.
For example:
I Love My Wife - ilmw
Now obviously this is not long enough but it provides an example of how to use this method.
Another method is the two or three word password. The two words selected should not be directly related to you. So no names, or addresses, etc.
Examples:
SkyMaster
NavyOrange
foryourconsideration
For additional security, you can substute numbers for some letters. Number 1 or the ! makes a good substitute for L or I. 2 can be substituted for the word to “to” as in 2day. 3 can replace the letter E (looks like a backwards E. Zero can replace the letter o. So:
SkyMast3r
Navy0range
4yourconsiderat!0n
Mixing in different foreign language words also helps.
I’m getting more into oddball pass phrases myself.
In a couple of months, I hope to take the Security plus test and try to get away from break/fix. Granted I have been blessed to have a good job paying well for help desk and fixing stuff but I can do better.
