The SecurID PIN is conceptually similar to a PIN that you might use for financial transactions. It is a number that only you know that helps to identify you.

The Personal Identification Number (PIN) is a unique 4- to 8-digit identifier that only you know. Your PIN can be of your own choosing, or system generated by RSA Authentication Manager depending on your RSA token policy. If you create your own PIN, follow the locally established rules for creating a valid PIN, including the number of characters, the reuse policy, and so forth.

Your security administrator can clear and reset the PIN as needed, so it is possible that your current PIN is invalid and you need to change it.
