Proton reported a problem on July 10, 2026, that knocked out login access to nearly all of its services at once. The company posted a notice at 15:35 CEST (Central European Summer Time) saying the team was investigating. Proton Status

Proton offers a bundle of services: email (Proton Mail), a calendar, cloud storage (Proton Drive), a password manager (Proton Pass), a VPN, and a few other tools. When the outage hit, people couldn't log into any of them. That includes the Web versions, phone apps, and desktop programs—basically every way to access these services stopped working.

Why did all of them go down at once? The most likely explanation is that they all rely on the same login system—a central "front door" that checks your username and password, and then lets you into whichever service you're trying to use. When that central login system broke, everything locked at the same time.

Proton sent out a few quick updates (at 15:38, 15:39, 15:40, and 15:42 CEST) but didn't say exactly what went wrong. The company's engineering team was still working to find and fix the problem. You can follow updates on Proton's status page, which runs independently of Proton's main systems so that updates can be posted even when everything else is broken. Proton Status

Proton's key feature is that it uses strong encryption—meaning the company itself cannot read your emails or files, even if it wanted to. That's good for privacy: a login outage doesn't expose your data. But it also means there's no shortcut to get you back in. Unlike some other services, Proton can't just let you in through a back door to rescue your account. You have to go through the front-door login system, and if that's broken, you're locked out.

When your password manager and your email service both go down at the same time, that's more painful than if they were separate companies. If you use Proton Pass to remember all your passwords and Proton Mail for your email, you lose both simultaneously. That puts Proton's team under real pressure to fix it fast and explain what happened.

Once the outage is fixed, the real story will be the postmortem—Proton's public explanation of what broke and why. The company has a good record of being transparent about these things, and this incident will get close attention because so many services were affected at once.

As of now, Proton has not said when the service will be back, and the outage is still ongoing. We will update this story as Proton posts further information.
