The challenge can be one of the following:

- Fixed - The device has requested the CMP server for a certificate (including a password challenge), the CMP server then validates the password and will issue this certificate. When "Fixed" is selected, the challenge password is used for each device request.
- Random - The device has requested the CMP server for a certificate (including a password challenge), the CMP server then validates the password and will issue this certificate. When "Random" is selected, each request will contain a different challenge password.
