What is PassLogic?

PassLogic is an authentication platform that provides strong security and operational efficiency. It has 4 main components:


The PassLogic Authentication Method

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

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 his or her 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:



Users can choose any sequence of cells from the grid when creating their secret patterns:


In the example below, the user, Alice, has selected a V-shaped pattern:

Alice will now have a new password each time she logs in.

The only thing Alice needs to remember is her secret pattern.

The PassLogic method provides the security of one-time passwords without the costs of provisioning and maintaining hardware or software tokens.

Adding a Static Password

It is possible to prepend or append a static set of characters to the password:

This feature can be used to comply with a policy that requires passwords that include alphabetic characters or special symbols.
