    Proton Pass — Secure Password Manager

    Last updated: March 11, 2026

    Most people reuse the same handful of passwords across dozens of accounts. If even one of those services gets breached, attackers can try your password on every other site you use — a technique called credential stuffing. A password manager solves this by generating, storing, and auto-filling strong, unique passwords for every account.

    Proton Pass is an open-source, end-to-end encrypted password manager built by the team behind Proton Mail and Proton VPN. It goes beyond storing passwords — it also protects your identity with email aliases, built-in 2FA, and a zero-knowledge architecture that means even Proton cannot see your data.

    What Is a Password Manager?

    A password manager is a secure digital vault that stores all your login credentials in one place. Instead of remembering dozens of passwords, you remember one master password — and the manager handles the rest.

    It generates strong, random passwords for every account, auto-fills them when you log in, and syncs across all your devices. This eliminates the two biggest security mistakes people make: reusing passwords and choosing weak ones.

    One Master Password

    Remember a single strong password. The manager encrypts everything else behind it.

    Auto-Generated Passwords

    Create unique, complex passwords for every site — no more "password123" or your dog's name.

    Autofill & Sync

    Automatically fill login forms across your phone, laptop, and browser — no copy-pasting.

    Secure Notes & Cards

    Store credit cards, secure notes, and other sensitive information alongside your passwords.

    Why Is Proton Pass Considered Secure?

    Not all password managers are created equal. Here's what sets Proton Pass apart from most competitors:

    End-to-End Encryption Everything in your vault — passwords, notes, email aliases — is encrypted on your device before it ever reaches Proton's servers. Proton never sees your data in plaintext.
    Zero-Knowledge Architecture Proton cannot read, access, or hand over your vault contents — even if compelled by a court order. They simply don't have the keys.
    Open Source & Audited The entire Proton Pass codebase is open source on GitHub. Independent security firms have audited the code, and anyone can inspect it for vulnerabilities.
    Swiss Jurisdiction Proton is headquartered in Switzerland, which has some of the strongest privacy laws in the world and is outside the Five Eyes / Fourteen Eyes surveillance alliances.
    Built-in 2FA Authenticator Proton Pass includes an integrated TOTP authenticator, so you don't need a separate 2FA app. Your 2FA codes are encrypted along with your passwords.
    Email Alias Protection Generate unique email aliases for each account. If a service gets breached, your real email address stays hidden and spam-free.

    How Does Proton Pass Work?

    Here's a simplified look at what happens behind the scenes when you use Proton Pass:

    1. You create a master password — This is the only password you need to remember. It's used to derive your encryption keys locally on your device.
    2. Encryption keys are generated locally — Proton Pass uses bcrypt and SRP (Secure Remote Password) to derive your keys. Your master password never leaves your device.
    3. Your vault is encrypted before upload — Every item — login, note, alias, credit card — is encrypted with your keys before being sent to Proton's servers.
    4. Sync across devices — Your encrypted vault syncs across all your devices. Each device decrypts locally using your master password.
    5. Autofill in your browser or app — When you visit a login page, Proton Pass detects the site and offers to fill your credentials — securely and instantly.
