Your certificates will be closed if you enter your PIN incorrectly three times. If you forget your PIN codes, you won’t be able to use your card for authentication or digital signatures.
If your PIN is blocked, you’ll see a message in the ID-card utility together with details of the blocked certificate. Click 'Revoke blocking' and follow the instructions on screen:
The revocation window will open
Enter your PUK code
Enter your new PIN code twice - PIN codes must only include numbers, PIN1 must be 4-12 digits long, and PIN2 must be 5-12 digits
If everything is successful, a corresponding message will be displayed (If not, follow instructions in error messages until the code change is successful)
