Strong passwords are crucial to prevent email hacking. It's often said that passwords shouldn't contain words that appear in dictionaries, or obvious numbers such as your date of birth, the date you got hired by your current employer, your telephone number, or your wedding anniversary. A seemingly random string of letters, numerals and punctuation marks is ideal. But how to devise a password which is so easy to remember you won't need to write it down? Here are some ideas. All the passwords shown here are examples only; none of them resemble the actual passwords I use for my own web-based accounts.
Draw inspiration from foreign languages
I speak a little Korean, and have considered protecting myself against hacking by deriving a password from my Korean name. When spelled according to the Revised Romanization / Ministry of Culture system, it's Choi Man-young. That obviously lacks numerals, so improvement by incorporating a significant date makes sense. My year of birth is far too easy to discover and therefore insecure. Perhaps choi19man1young0 would be a good, safe option. The year 1910 is when Korea was annexed to became a Japanese colony. It's a moment in history drummed into the head of every Korean, but not a date any hacker is likely to link with an educator and writer from the Canadian Prairies who now lives far from Korea.
Draw inspiration from history
To thwart hackers, obscure events are obviously preferable to the landmark dates everyone learns at school. Americans tempted to use ww2194119145 (no prizes for guessing what those letters and numbers stand for) would do much better if they selected gba111963 (Abraham Lincoln made the Gettysburg Address on November 19, 1863). The history you use to inspire your password doesn't have to be political or military. If you love sport, find something that's easy to remember and work from there. I like blu10gry90, which to me is a reference to the Winnipeg Blue Bombers having won the Grey Cup ten times, the most recent triumph being 1990. The Blue Bombers are a Canadian football team. (Canadian football isn't quite the same as American football; among the differences are that each team has 12 players instead of 11.) The Grey Cup is Canada's Superbowl, the annual championship game featuring the teams which won the East and West Divisional playoffs.
There's another way to confound hacking attempts: Use dating systems other than the Gregorian calendar. If you look at Wikipedia, you'll find dozens of calendars, including the Islamic one, the Thai solar calendar, and not one but three Hindu calendars. The Chinese lunar calendar is still in common use in Hong Kong and Taiwan to plan religious events and determine if a particular day is suitable for a wedding, funeral or other occasion. The UK continues to use a regnal calendar for dating new laws passed by Parliament. If you met your significant other five years ago, 57Eliz2 could work as part of a password.
Remind yourself of life goals
A password that has to be entered on a daily basis is an opportunity to remind yourself of something you hope to achieve. Here are three examples:
s2tdsicl17P = Stick to the diet so I can lose 17 pounds
asp&ty2twhu = Always say please and thank you to those who help you
4pscape7d = For Pete's sake, change all passwords every seven days!
