      Good passwords are hard to remember. A pattern that makes a password memorable is likely to make it vulnerable to attack.

      A rather interesting scheme and allegedly secure.

          Solution: Always use a random password generator. Then every time you want to access a website, click on 'forgot my password'. ;P

            You could do this without any maths by having a particular song in your head that you know all the words to (for example the national anthem) then for any given site, find the first instance of the first letter of the site name in the song (e.g. for codeproject it could be "God save our gracious queen" then take the number of letters after that letter that correspond to the number of letters in the site name (e.g. for codeproject this would give "cious queen", trim spaces and replace vowels with the ordinal of the vowel in aeiou. So - after all that you get the uncrackable password: c345sq522n Then don't forget not to reveal this method and password to the whole world. :doh:

                  I was actually thinking that Duncan's solution below was a pretty good idea. The problem is, is I don't know the words to God Save the Queen so it would not work for me. :laugh:

                    Actually this is true, but we need to make use of multiple words. Password might have only one word in it, but we can have more than one word appended and mixed so that we can memorize it, and can be safe too.

                        "When I was 5 years old, my mother always told me that happiness was the key to life. When I went to school, they asked me what I wanted to be when I grew up. I wrote down 'happy'. They told me I didn't understand the assignment, and I told them they didn't understand life." - John Lennon

                                    Its good practice to use secure passwords that are a mixture of letters, numbers, and punctuation. Got that. Its good practice to not use familiar words. Got that. It is good practice to have different passwords for each site. Got that. It is good to make passwords as long a possible. Got that. Great! I have 167 different passwords using random characters, each 20 bytes in length. Oh. Did I forget. You shouldn't write down your passwords, either. AWESOME! At work I use the same 8 character password across all servers and mainframe so I only have to remember one. It comprises upper lower characters, numbers, and punctuation. Each character is typed switching hands, so right left right left, and so on. And it changes every 45 days. At home, I use four or five variants of the same complex password that is 14 characters in length. I think I'm good until some site is hacked and its all exposed.

                                      An interesting idea, but seriously, when's the last time you heard about hackers getting into an account by brute force cracking the password? Its all about social engineering and vulnerabilities like bashbug. I like his idea, I might even use it someday, but since the passwords are not really the weak link in the security equation anymore, it seems like a lot of effort to make yourself no more secure.

                                      We can program with only 1's, but if all you've got are zeros, you've got nothing.

                                        Good passwords are hard to remember. A pattern that makes a password memorable is likely to make it vulnerable to attack.

                                        A rather interesting scheme and allegedly secure.

                                        I use multi-factor authentication. My finances are on my Surface Pro. I always run Quicken on an external monitor, and Quicken isn't smart enough to reposition the launch location when the monitor isn't connected. As for my passwords, they're all in Norton on my old laptop.

                                          I still prefer using Base64: CodeProject ==> Q29kZVByb2plY3Q= Done.
