PassWindow is...

  • An incredibly simple, yet also extremely secure dynamic password solution
  • Free from client hardware or software, requires no batteries and cannot malfunction
  • Able to securely authenticate the client to the server AND the server to the client
  • Able to transmit transaction information securely to the user through the visual challenge

How does it work?

  • PassWindow is a unique key pattern printed on a transparent section of a standard identity card.
  • Users simply hold their card over a generated pattern image on any display to reveal a new series of digits – a single-use password.
  • Users enter this new unique password to authenticate securely.
  • Unusual monitor sizes are easily handled with a simple adjustment of the challenge image which is then saved to a cookie or user database. Try it yourself with our online demo!

  • In the wake of recent security disclosures, PassWindow has the security advantage of your company being able to print cards in house with a standard card printer. Avoiding any potentially compromised outside manufacturers.
  • Do away with password memorization – 2FA authentication obviates necessity for passwords.
  • Usable on any electronic display – PCs, laptop, mobiles – no specialized software or hardware required.
  • Works with all graphical operating systems and web browsers
  • Disaster proof – PassWindow can continue to operate without Internet, communications, or even electricity. Users simply authenticate off printed challenge patterns using their same card keys.
  • No need to redirect the user away from your website for third-party verification – PassWindow challenge patterns are delivered directly from your own secure web server.
  • Excellent fallback protection for security questions, which are currently the weakest security link in many authentication systems.
  • Extremely durable, no flexing problems with internal electronics, waterproof and pressure proof.
  • Unlimited working life – no batteries or electronics, so lifespan is not limited to battery life.
  • Easy to understand – With most software and hardware authentication systems being beyond the understanding of the average user, authentication acceptance and online trust levels are low – PassWindow provides a security mechanism that even children can easily understand.
