Authorization levels for form management

Is it possible to manage authorization to forms by grouping?

For example I have 3 departments in my organization and each department should only be authorized to create and edit its own forms.

You can share your forms with the sub-user accounts. Each department can create its own account and you can share with them your forms. You can select the forms you want to share with each sub-user account. Inside of this guide, you can find how to share the forms:

How to Share Forms with a Sub-Account User

The sub-user account limits are:

Starter/Free plan - 1 sub-user account

Bronze plan - 3 sub-user accounts

Silver plan - 10 sub-user accounts

Gold plan - 100 sub-user accounts

I would suggest you to check other limits on our Pricing page.
