1. Download the file ‘Certificate_Password_Change.zip’.

2. Extract the file ‘Certificate_Password_Change.zip’ to your desktop or another folder.

3. You now have two options for changing the password:

• Copy the certificate to the folder ‘Certificate_Password_Change’ where you want to change the password.
• Run the file ‘change_password.bat’ (double-click).

Or

• Drag the certificate onto the file ‘change_password.bat’ (see screenshot)

4. Follow the instructions in the script and first enter the old password and then the new one twice
5. Please note: The password has only been changed for the file that you copied to the folder or dragged onto the file. All other copies of the certificate (e.g. those on the USB stick) still have the old password and should be deleted.
6. For security reasons, a backup of the certificate was created beforehand. It is located in the same folder as the certificate and has the file extension ‘.bak’.
The file can also be deleted once the certificate has been successfully created.
