The MOOCs available on POK are free and open to everyone. Upon completion of the MOOCs, a certificate is issued, either as an Open Badge or a Certificate of accomplishment (this is specified in each MOOC's information page).
To attend a MOOC, you need to access with a verified personal account. You can log in using a Polimi account, an eduGAIN account, or through SPID/CIE ("How do I access POK?").
If you don't have any of the above accounts, you can create a POLIMI account, regardless of your affiliation with the institution ("How can I create a Polimi personal account?").
Once you've logged in with your verified personal account, you can independently enroll in the courses that interest you ("How do I enrol in a course?"). After that, you can immediately access the content and use the materials whenever and wherever you want.
