No. Access to TutKit.com is personal. Only the owner himself is granted the right to use it; it may not be passed on.
Good news: You are welcome to add additional participant places to your membership as part of the membership administration for a fee. You can freely assign these to participants, who will then receive their own access to the conditions of your chosen model variant. This makes sharing even more fun: the download quota of each participant is not affected by the other participants.
Participants or invited persons can also be removed and reassigned by the owner at any time. To do this, select the relevant options in the member administration.
