Super Password
I describe here a practical way to set up a Super password, which must be easily memorized by people. People can combine two different or same passwords into a new Super password with long digits. People are using several passwords for more than 50 accounts, according to the statistics. Their passwords were made by themselves, consisting of easy-to-memorized letters, numbers, and symbols. Therefore, the Super password is easy to be memorized but is troublesome to be typed.
Theoretically, I cannot prove the strength of the Super password. What I can do is to check its strength by use of public password checkers. In my experiment, I have used 3 different password checkers on the Web, which investigate the time to crack the password by use of commercial PCs. I prepared 4 different passwords, which are the name of a person, the date, the word with the symbol, the word with numbers. The number of password characters is so small that all 3 password checkers crack them in a short time.
As shown in the above figure, 3 simple Super passwords are made by the use of 2 different passwords. The results of the same password checkers show quite a long time to be cracked. It seems that no password checker can separate a password into smaller two passwords.
Please try to use the Super password and give me your comment on this proposal.
