The PassLogic Authentication Platform


PassLogic Authentication: Tokenless One-Time Passwords

A user creates a secret pattern by selecting a sequence of cells from a grid:

The user can select any sequence of cells from the grid for the pattern – the same cell can be selected multiple times.


Each time a user goes to log in, the grid will be filled with a new table of random numbers and will be displayed above the password entry field.

The user’s password is the sequence of numbers in the random number table that corresponds to their secret pattern. Since the random number table is refreshed every time a user goes to log in, the password will be new for each login:


Adding a Static Password

The password can be strengthened by prepending or appending a static set of characters to it.

In the following example, the user has selected an L-shaped secret pattern and appended ‘PassLogic’ to it.
