I would like to know if it is possible to force the participants of the meetings, whether or not to add the name, surname and email. As forced camps. On the other hand I would like to know if you can synchronize with a database, so that only those with a specific email participate.
@TACTICA GoToMeeting was designed with limited security options, as mentioned in this existing Community thread. I don't believe there are any plans to for registration with this service because it makes the join flow more difficult for most participants. If you need a higher level of security, you might consider trying GoToTraining or GoToWebinar, which have options like required registration, and approval systems.
