For access to health data, the Dutch government requires that your data is protected as best as possible. These strict precautions to protect your data are based on the need to verify your identity.

By scanning an ID with your smartphone, it can be verified that you are actually the person linked to the health data within your chosen PHE. This way you can be sure that no one else has access to this data.

An SMS as a means of authentication (also called a second factor) is considered insufficiently secure.
