Step 3
To access any resources (data or commands) on the SIM, the EAP-SIM supplicant must provide a valid
PIN to the SIM card, which must match the PIN stored on the SIM. Select one of the following options
to specify how the EAP-SIM supplicant should handle the SIM card’s PIN:
•
Ask for my PIN once after I turn my computer on (recommended)—The software does not
permanently store the PIN. It prompts you for the PIN once, on the first authentication of every
session, where a session is defined as the time between power-up and shutdown or reboot.
•
Ask for my PIN every time the network asks for authentication—The software never stores the
PIN; it prompts you for the PIN every time an EAP-SIM authentication is performed. This option is
not recommended if your client will be roaming between access points or if session timeouts are
implemented (such as for accounting and security purposes).
•
Let me give my PIN to the computer now and never ask me again; PIN will be encrypted and
stored on computer (not recommended)—You need to enter the PIN only once, in the Enter PIN
edit box below this option. The software stores the PIN in the registry and retrieves it from there
when required. If you select this option, you must enter the PIN now. The PIN is validated when an
authentication attempt is made.
Note
This option is not recommended because it enables others to use the SIM without knowing
the PIN.
