LastPass 
Dashlane Proton Pass is a privacy-focused password manager developed by Proton AG, bringing the company’s zero-knowledge encryption expertise to credential management. Unlike password managers that store your vault on servers where company employees could theoretically access it, Proton Pass encrypts everything on your device before synchronization—meaning your passwords, notes, and personal data remain readable only by you.
Built by the team behind Proton Mail, Proton Pass implements end-to-end encryption for all vault contents including passwords, usernames, URLs, notes, and credit card details. The encryption keys are derived from your master password and never leave your device. Even Proton cannot decrypt your vault, providing protection against data breaches, rogue employees, or government demands.
Proton Pass is headquartered in Geneva, Switzerland, with all encrypted vault data stored on servers in Switzerland, Germany, and Norway. This places your credentials under some of the world’s strongest privacy protections, including Swiss FADP and EU GDPR. The service is ISO 27001 certified and SOC 2 Type II attested.
The password manager includes features that go beyond basic credential storage: unlimited hide-my-email aliases (powered by SimpleLogin, which Proton acquired), built-in 2FA authenticator, secure password generator, Dark Web Monitoring for breach alerts, and Proton Sentinel for advanced account protection. Native apps are available for all platforms, with browser extensions for Chrome, Firefox, Safari, Edge, and Brave.
Key Features
- Zero-Knowledge Encryption: Vault encrypted before sync, unreadable to Proton
- Hide-My-Email Aliases: Unlimited email aliases to protect your real address
- Built-in 2FA: Integrated authenticator for one-time passwords
- Dark Web Monitoring: Alerts when credentials appear in data breaches
- Proton Sentinel: AI-powered protection against account takeover
- Secure Sharing: Share vault items with trusted contacts
- Cross-Platform: Apps for all major platforms and browsers
Privacy Highlights
Proton Pass encrypts your entire vault client-side before any data touches Proton’s servers. The encryption uses industry-standard algorithms (AES-256, Argon2) with keys derived from your master password. This zero-knowledge architecture ensures that even a complete server breach would expose only encrypted, unreadable data.
The integration with SimpleLogin provides unlimited email aliases, allowing you to create unique addresses for every service without revealing your real email. This prevents cross-site tracking and limits the damage from individual site breaches.
