How it works?

The user installs and activates the BidiKey application on their smartphone.

  • The BidiKey application is protected in the smartphone by the use of a personal password.

The user facilitates their user name to the service provider.

A cryptographic challenge is shown in the screen with the appearance of a bidimensional code (ie QR code).

The user captures the bidimensional code with their phone camera.

The challenge contained into the bidimensional code can only be decrypted by the user key managed by the BdidKey application on the user's smartphone.

The user gets the OTP and type in, being not required to remember any password or PIN to access to the service.

  • If the user introduces a wrong OTP within a limited number of attempts, the service will be blocked.
