In order to improve safety, the Cl@ve PIN system has changed its behavior, configuring itself as a single-use key (OTP), so as to ensure that whenever authentication is requested a new PIN must be obtained.
In this way, the PIN you receive on your mobile phone can only be used once to complete access to the system.
In addition, you must use the PIN you received before 10 minutes, since after that time, if you have not reached Cl@ve, you must request a new PIN.
Remember that once you have been identified using the PIN, you can access the services that allow Cl@ve until you are disconnected from the Electronic Headquarters or close your browser.
