You can create up to 100 users in yve for your account. To do this, click on 'User -> new' enter the personal data and enter an abbreviation and the password. For users, the login is performed via the email, so each user must have a valid email, which is unique in your account.
Permissions in yve
Yve strictly separates between the following person types:
Users: organize the events, set the event, and manage the participant process
Contacts: can be assigned as participants to an event
For security reasons, these two types can not access the contents of the other person. For this reason, you must first create a test contact themselves in order to test an event as a participant.
The login masks are also different (replace your account name with your account name):
Users: log in via https://accountname.yve-tool.de
Contacts: log in via https://accountname.yve-tool.de/login
