A Firefox password manager for all your data — not just passwords
Easy to use
✓ Protect your passwords, notes, credit cards, and identity with Swiss privacy standards
✓ Sync and access your encrypted data across all your devices
✓ Quickly transfer your passwords from Firefox or other password managers to Proton Pass
Zero-knowledge architecture
Proton Pass secures your passwords, usernames, web address, and metadata with 256-bit AES-GCM encryption and end-to-end encryption. All cryptographic operations happen locally on your device, so unencrypted data never leaves your control or reaches Proton’s servers.
Only you can access your private information, including your Proton Account password. In the unlikely event of a data breach, there would be nothing for attackers to steal.
Dark Web Monitoring
Part of our Pass Monitor security feature, Dark Web Monitoring continuously scans online databases for any instances where your email addresses — and any associated information, such as credit card details — have been exposed in data breaches. This applies to Proton’s 19 email domains (such as @pm.me or @protonmail.ch) and, for paid plans, to custom email domains with your consent. If your data is compromised, you’ll receive a prompt alert, allowing you to act quickly to prevent identity theft or unauthorized access.
Password sharing
Securely share passwords, credit cards, or notes with others, even if they don’t use Proton Pass. Share single items via end-to-end encrypted links, or grant vault access by email, with options to set expirations, limit views, control access, and revoke it anytime.
