Get started with Proton Duo
When you introduce a friend or loved one to Proton Duo, you both save on unlimited privacy. Duo includes the premium version of Proton Mail, Calendar, VPN, Drive, Pass, and Wallet for two people, plus 2 TB of storage to share.
You get to decide what to share with each other. Both accounts have separate sign-in details, and neither user can see the other’s data.

Who can I invite to my Proton Duo plan?
With Proton Duo, you can invite another user to your plan. All they need to join is a Proton Account. If they don’t already have a Proton Account, they can easily create one for free.
Do I need to have a custom email domain to get Proton Duo?
No, you don’t. The Proton Duo plan supports up to three custom email domains, but you don’t need a custom domain to invite family members.
How does storage space work?
Proton Duo gives you 2 TB of storage space to share with your partner. When you add someone else to your plan, as the administrator of the plan, you’ll be prompted to allocate storage space. If your needs change, you can then adjust how much storage each of you has at any time.
Can the other member of my Proton Duo plan see my emails, files, events, or passwords?
Each member of a Proton Duo plan has their own separate account. Emails, files, and events remain encrypted with their private key. So you can’t see the data from the other person you invited, unless they choose to share it with you (by sharing, for example, their calendar or Proton Drive files).
Can I leave a Proton Duo plan?
If you were invited to the Proton Duo plan, you can leave at any time. Your account will be downgraded to a 30-day trial of our Proton Unlimited(new window) plan. You’ll keep all your files and folders but will lose access to the features and storage space of Proton Duo. If you’re the administrator of a Duo plan, you can cancel your subscription. Note that if you added someone else to your plan, they will be removed from your family group when your plan expires.
What happens to my paid subscription when I join a Proton Duo plan?
When you accept an invitation to join a Proton Duo plan, we credit you the remaining months of your current subscription.
Can I change the primary administrator of my Proton Duo plan?
No, you can’t change the primary administrator of your Proton Duo plan.
