2. Click on Start, select All Programs, choose Gemalto, then Classic Client and click on Classic Client Toolbox.
3. In the Classic Client Toolbox window, click on Card Administration.
4. In the next screen, select Pin Management and from the right-hand side of the window choose Change PIN; then click on Next.
5. In the PIN Management window, enter the current PIN code of the device (the one printed on the letter you received from certSIGN) in the field Current PIN.
6. Enter the new PIN code (at least 6 characters) in the fields New Pin and Confirm New PIN; then click on Change PIN.
7. In the next window, click the OK button.
