This Maven Analytics group plan uses shared credentials, meaning you log in to a shared account that has already been upgraded to Pro. Just use the email and password provided by admin once the group is full and payment is verified. One slot is for one person, and you can take any course available on Maven Analytics during the package period.
Shared account rules: do not change the password or email given to you, do not log out other devices, and do not modify account information. Doing so can cause other group members to lose access or trigger Maven Analytics security detection. As long as everyone follows the rules, access stays stable until the end of the period.
Right now, only the 1-user or private package is open, so you get your own slot without sharing. The multi-person group package is still being prepared and will open soon. Once group packages are available, this page will show the group tier with an even cheaper per-slot price.
