Designed and hosted in Switzerland, Proton Drive is developed by the team behind Proton Mail and Proton VPN — trusted by over 100 million users worldwide. We’re independent, open source, and committed to keeping your data safe from surveillance and vendor lock-in. Proton Drive helps you stay compliant, with support for: - GDPR, HIPAA, ISO 27001, NIS2, and DORA - Verified SOC 2 Type II audits - No complex setup. No third-party tools required. Built for security teams, law firms, healthcare providers, consultancies, and privacy-conscious organizations of all sizes.

Proton Authenticator is a privacy-focused two-factor authentication app that generates time-based one-time passwords, thus providing an additional layer of security to online accounts beyond standard passwords and allowing users to protect their accounts across various devices. As an open-source application that uses end-to-end encryption, it guarantees that all cryptographic operations and secret keys are processed locally, meaning that even Proton's developers cannot access users' unencrypted 2FA data, thereby emphasizing a commitment to transparency and strong privacy by design. Users can synchronize their 2FA codes across multiple devices through encrypted backups, utilizing options such as iCloud or a Proton Account, while also having the capability to import codes from other authenticator apps and export them when needed, which grants them flexibility and control over their 2FA credentials without being locked into a single provider. In addition, Proton Authenticator is entirely free, with no advertisements or tracking, and features secure options like biometric locks and offline access, allowing users to generate login codes at any time, even without an internet connection. This makes it particularly appealing for individuals who prioritize security while efficiently managing their online accounts, as it combines usability with robust protective measures. Furthermore, its commitment to user privacy and transparency sets it apart in a market where many alternatives may compromise these values.
