The Mentimeter account is personal, meaning that you are not allowed to share a single account with other users. Sharing of a single account is a violation against our Terms of Use and each presenter needs to create their own Mentimeter account, using their own email addresses, so that we can ensure a stable platform.
Also, every presenter needs their own accounts for security reasons. For example, results might be accidentally wiped out if another presenter logs in and changes the questions after any previous sessions conducted with the same presentation.
If you and your colleagues need to work on a presentation together, you can add several licenses at the checkout with the Mentimeter Basic and Pro plans. You and your workspace will get access to workspace sharing features.
