Proton Duo Discount: Coupons and Deals 2026

If you and a partner, spouse, or family member are both looking to upgrade your digital privacy, Proton Duo is the smartest way to do it. You get full Proton Unlimited features for two separate accounts — at a price that beats buying two subscriptions individually.

What Is the Proton Duo Discount?

Proton Duo is a shared plan that gives two people complete access to every Proton service — encrypted email, VPN, cloud storage, calendar, and password manager — under one subscription. Each user keeps a fully private, independent account. There is no cross-account data sharing, just a shared bill.

The savings are significant. Two separate Proton Unlimited plans would cost considerably more per year. With Proton Duo, you save roughly $60 annually compared to paying for two individual plans — and there is currently a special promotional rate of €14.99/month on the one-year plan, locked in as a permanent discount for the life of your subscription.

Proton Duo Pricing

• 1-Year: €19.99/month (save ~20%)
• Special Promo: €14.99/month on the 1-year plan

All plans come with a 30-day money-back guarantee, so you can try Proton Duo completely risk-free.

What’s Included

Both users on a Proton Duo plan receive the full suite of Proton’s premium services. Here is a breakdown of what each person gets:

Proton Mail Plus

Up to 15 email addresses, support for 3 custom domains, advanced inbox filters, hide-my-email aliases, and an encrypted calendar. All messages are end-to-end encrypted by default.

Proton VPN Plus

Access to over 15,800 servers across 126 countries, with up to 10 simultaneous device connections. Includes a built-in ad and tracker blocker (NetShield), streaming support for Netflix and other platforms, and Secure Core routing through Switzerland for an extra layer of protection.

Proton Drive

2 TB of encrypted cloud storage shared between both accounts. Every file is encrypted before it leaves your device. Features include automatic photo backup, file version history, password-protected sharing, and a built-in document editor.

Proton Pass

A full-featured password manager with unlimited logins, a built-in two-factor authentication tool, dark web monitoring, and secure credential sharing. No separate authenticator app needed.

Why Proton?

Proton is headquartered in Switzerland, placing it outside the reach of US and EU surveillance frameworks. Its applications are fully open-source and independently audited. The company recently transitioned to a non-profit foundation structure, meaning its only incentive is protecting your privacy — not monetising your data.

Proton was also founded by scientists and engineers from CERN, which says a lot about the technical rigour behind the product.

Is Proton Duo Worth It?

If two people in your household are going to use Proton, this is simply the better deal. You get the full premium experience for both users, 2 TB of shared encrypted storage, separate private accounts, and the ability to share a custom email domain — all for less than two individual subscriptions. The $14.99/month promotional rate makes it even more compelling as a long-term commitment.
