How to enable multi-user support for professional plans

Multi-user support is available on ProtonMail Professional and Visionary plans. 

  • Users within a Visionary plan can add up to six users.
  • Our Professional plan allows only one user by default, but you can add up to 5000 users, who you can then add to your organization. (If you wish to add more users, please contact to discuss your needs). 

To enable multi-user support for a Professional plan, you must:

1. Add at least one user to your plan.
