CheckPW.com is a two-way password system.
Most transactions involving a password are one-way: a user offers a password and the receiver verifies whether it is correct or not. Using CheckPW.com allows both parties to verify a password without disclosing the password to the other party.
CheckPW.com is first-of-its-kind, free, easy to use and 100% confidential.

Use CheckPW.com if:

• If you are, in fact, a secret agent
• As an icebreaker at meetings and conventions
• Anywhere passwords are used or secrets need to be confirmed

Examples:

1. Salary Inequality:
   “How much are they paying you?”
   “Wait, how much are they paying you?”
   
   Pat and Sandy are new hires at a company. Each is concerned they were treated unfairly and hired at a lower salary than the other. Both would be pleased to know that they received a higher salary than the other. They would feel neutral knowing that they received the same salary.
   Solution: Pat and Sandy use CheckPW.com to see if their salaries match.
2. Warning Harry Potter
   Dobby the house-elf wants to warn Harry Potter about a serious danger. But he is not allowed to reveal the name of the villain!
   Solution: Dobby puts the villain’s name into CheckPW.com. Harry guesses correctly.
   
   (See Harry Potter and the Chamber of Secrets, Chapter 18.
   "I've just got one question, Dobby," said Harry as Dobby pulled on Harry's sock with shaking hands. "You told me all this had nothing to do with He-Who-Must-Not-Be-Named, remember? Well --" "It was a clue, sir," said Dobby, his eyes widening, as though this was obvious. "Was giving you a clue. The Dark Lord, before he changed his name, could be freely named, you see?")
3. Secret Handshake
   Some clubs or groups use a secret handshake to identify fellow members. But these are easy to steal by an Evil Agent after a few attempts.
   Solution: Use CheckPW.com instead!
