Question

What is the difference between user roles: Owner, Administrator, Developer, Billing Manager, and Support?

Answer

"Owner" role

Each Twilio account has only one user in the Owner role. The owner is automatically set to the email account used to setup the account, and has access to everything. 

Additional user roles

Additional users may be added to your account with varying levels of permissions. Each new user must be assigned one of the following roles:

• Administrator: Full access to invite and revoke access for new users, see billing history and make changes, and update project settings.
• Developer: Access to only the required project details for developing with Twilio - API credentials, phone numbers, development tools, logs, and usage.
• Billing Manager: Access to only the required project details for handling billing requests - logs, usage, and billing history and settings.
• Support: Access to logs and usage. 

Enhanced RBAC Public Beta

Role Based Access Control (RBAC) is available as a public beta release. With it you can grant access to Twilio resources in a granular way and prevent access to other resources. Twilio RBAC lets you adopt the security principle of “least privilege access” for users in your Twilio accounts, managed by a Twilio Organization.

To learn more on what roles are available and the way to assign them to your users - you can check the Access Control documentation.
