How It Works


Your customer generates a Password Card

Our service instantly creates a randomly generated, unique grid.

Printable/downloadable password cards fit perfectly in a wallet, or use the mobile 2FA app to create one-time-use password cards.


You generate a random PIN

Using our API, a random PIN is generated that is usable by your customer’s unique Password Card. You can set how many PIN characters are required.

** 3 digit PIN with PW is safer than 5-digit TOTP PIN **


Your Customer Enters the PIN

Your customers use their Password Card to match the position of the characters and enter the correct characters.


PIN Validation

Using our API, you validate the characters provided by your customer.

That’s it! No waiting on an SMS text that may or may not arrive, no reliance on unsecure third party systems, no costly digital PIN devices you must buy and ship to customers. Instant, safe, and easy!
