How It Works - 2-Factor Authentication Service


Your Customer generates a Password Card

Our service instantly creates a randomly generated, unique grid
of 16 x 16 or 16 x 34 characters.

These cards are printable and/or downloadable, and are
the size of a credit card so they fit perfectly in your
customers' wallets.


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.


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!
