How to grant educational licenses?

Question

IT education

There is a need to provide educational institutions with licenses for the service for free. Each student registers on the service under his own account. The term of the license should not exceed the duration of training in specific courses, the number of licenses should not exceed the number of teachers, laboratory assistants and students. The mechanism for granting such licenses should be as automated as possible.
For example, it is possible to determine its type by the email of the educational institution of the registered participant, but not all educational institutions provide their mail, not all students register in social networks under the educational mail.
A temporary promotional code will not save you from passing it on to unauthorized users. What mechanisms are used to issue academic licenses?

Answer 1

for Dreamspark, for example, you need to send a scan of your student ID and confirm it every subsequent year. and I don’t know how everything is arranged inside them, maybe there is a connection with the university to confirm the identity of the student.
