what i use. Very easy to memorize, works for 90+% websites
1. take two random words, e.g. Anarchist and Workshop
2. take whatever follows after the www at the website that you need the pw for, e.g. anandtech.com
3. with these these three words, decide to start at first, second, fourth position, and take the following four letters. For our example we choose to start from the third letter. This gives us :
arch
rksh
andt
4. add a symbol and two numbers. E.g. & and my birth month, 11
5. add all above together and capitalize the first letter. This gives
Archrkshandt&11
Note that the only variable is andt here. For citibank.com this'd be tiba, for blogspot ogsp. for a short website you can roll into the .com, .net or start from the beginning of the domain name.
Havent logged into origin since you played DA 3 years ago? Forgot pw? No prob. It'll be the fragments your two words + igin + &11
Sorry, if I'm unclear. It's early in the morning.
