Help Topic : 3. I want to have other TD's to manage my events. Should I share my organizer's username and password with the TD's?
No - you should not share your organizer's username and password with anyone. When you share the passwords with multiple people, the password can be leaked unknowingly. Anyone with your password can then mess up your organization's events and steal your PayPal secrets and SendGrid keys.
If you want to let other people manage a specific event, you use delegates.
