Develop an Algorithm for Your Online Passwords and Never Forget One Again

I am sure that most of you guys have dozens of passwords for different websites. Blogs, hosting plans, social networking sites, online services, forums, you name it. The problem is to remember what password is for what website (and using the same one all over the place would be crazy for security reasons).

A first solution is to use a password manager, as I recommended in the past. However, even using that I often end up losing passwords. This happens when I forget to sync my database of passwords between different computers, for example.

To solve this problem I am starting to use a technique to be able to know all my passwords automatically. How? By creating an algorithm to create the passwords.

Here is one example:

  • The first digit is the number of characters on the name of the website.
  • The second digit is “c” is the number in the first step was odd, and “t” if it was even.
  • The third digit is the last letter of the name of the website.
  • The fourth digit is “$” if the letter in the previous step was a vowel, and “%” if it was a consonant.
  • The last three digits are the first three letters of the name of the website.

Using the algorithm above, your password on Twitter would be “7cr%twi” and on Facebook it would be “8tk%fac”.

Once you start using the algorithm to create your passwords you will be able to remember any password by applying it again. Obviously the important thing is to make sure no one knows what your algorithm is (and that the algorithm is slightly complex).

    pwgen can generate a random, strong, long password. You can use the same password almost everywhere with a simple algorithm to keep it unique. (E.g. replace the third letter of the password with the third letter of the website.)

    The biggest problem I face is websites like that restrict the use of certain punctuation characters in the password… which means that password has to be unique, and weaker than the rest.

    I use the first letters of the words in the first line of a song. I vary it by using different verses or adding letters, numbers, and symbols.

    I always lose and forget my passwords, so these tips are really very helpful for me. I can’t believe I didn’t think about this before, even after watching Veronica Mars for its whole duration! haha Thanks, anyway. These info can really be handy.

    I think Dean @ Pro Copy Tips method is the quite good. It would be better if special characters are used. For example McSh9la4l+KWST or McSh9la4l@KWST…

    I think I a “code book” is nice. But I prefer soft copy instead. I have most of my password saved in an excel file protected by a strong password.

    Your this trick remind me my school days when we learn long words or point of long answers in this way.

    We try to create a meaningful words by the first letter and through this way we never forget.

    You wont believe this but some of answers are still in my memory.
