To help me remember passwords, I use lines from songs and use the first letter of each word, throw in special characters, numbers, and random caps. For instance, using a line from Yesterday (Yesterday, all my troubles seemed so far away), I might get: y-Amtss4a. That’s not long enough, but it serves as an example.
I used to work in a Dept. of Energy national lab. They had a project to test the security of all the labs. They sent infected CDs to random people at the labs and some people actually played the programs on them. This allowed them to get into the lab’s network. From there, my understanding is that they cracked passwords by encrypting all possible combinations of valid characters up to a certain length and created a table that they could search for people’s passwords. The more characters used, the longer it takes and the more storage it takes. It takes about 70x the effort/storage to crack passwords for every character more. Because I had a reputation as a power user, they targeted me and cracked my 8-character password. They were hoping I would have programs on my computer they could user to break into more stuff.
One day I saw my mouse pointer move without my assistance. I immediately disconnected my network cable and got a message saying the connection to a computer was broken. I later discovered it to be in Illinois. I called my support tech and our IS department went into action. Not knowing it was a test, I felt very guilty and wondered what I had done to get infected. I tried to clean up my computer and spent two weeks at it until they let me in on the secret. Then, they took my computer and destroyed the hard drive. I had to buy a new computer.
I later found out that I was the only one in all the national labs to catch them. I was just lucky to see them accidentally bump my mouse when I was using my computer. The fact that so many people put a random CD they got in the mail and ran the program on it did not sit well with DOE. After that, lab started testing us on a regular basis. About one in five people failed the tests.
I asked the people who cracked my computer how long of a password I should use. They said they could crack a 14-character password. I figured they were lying, so I changed mine to 16 characters. As this was over a decade ago, I imagine bad people can crack even bigger passwords with modern computers.
The moral of this story is to use long, random passwords. I highly recommend a password manager. I use Keeper and like it very much. It runs on all my computers and mobile devices and shares my passwords amongst them. I also strongly recommend you use two-factor authentication for your most important accounts.
