Is Proton Pass Really Safe to Use?

Yes — Proton Pass is very safe to use. It protects all data with end-to-end, zero-knowledge encryption , meaning only you can decrypt your vault, not Proton. Security is further reinforced with Argon2 key derivation, encrypted metadata, and optional features like Proton Sentinel for account takeover protection, passkeys, dark web monitoring, and granular sharing controls. Since Proton is based in Switzerland, it also benefits from some of the world’s strongest privacy laws. Combined with its open-source code and strong security design, Proton Pass gives you confidence that your passwords and sensitive information are kept private and secure.

Does Proton Pass offer a free plan?

Yes — Proton Pass includes a very generous free plan that stands out among password managers. Even on the free tier, you’re granted unlimited password storage and sync across unlimited devices, which is rare for no-cost offerings. The Free plan also includes core features such as a password generator, basic password health alerts (identifying weak or reused credentials), passkey support, and up to 10 hide-my-email aliases. While advanced extras like dark web monitoring, file attachments, and Sentinel are reserved for paid plans, the free version covers more essentials than many competitors’ locked-down free tiers. If you’re looking for secure, cross-device password management without spending a dime, Proton Pass Free is one of the strongest options available.

Does Proton Pass work offline?

Yes — Proton Pass does work offline, but only if you’re on a paid plan . Once enabled in the desktop or mobile apps, your vault is stored locally in encrypted form, allowing you to access saved passwords, notes, and aliases even without an internet connection. You can’t add new entries while offline, and the browser extension still requires connectivity, but for day-to-day access, the offline mode is reliable. Free plan users don’t get this feature.

Does Proton Pass support passkeys and hardware security keys?

Proton Pass supports passkeys , letting you store and use them across desktop, mobile, and browser extensions just like regular passwords, with secure syncing across devices. Hardware security keys (like YubiKey) can also be set up as a two-factor method to protect your Proton account login, but they don’t currently unlock the Proton Pass vault itself. This means passkeys are fully integrated into everyday use, while hardware keys are limited to securing account access.

Can I share passwords or vaults with other people?

Proton Pass makes sharing both secure and flexible . You can create shared vaults or individual entries and invite people to access them. The system uses role-based permissions, so you can define whether someone gets view-only, editor, or admin rights. This means you can safely let someone view a shared streaming account without letting them change it, or grant full control to another trusted person. Sharing is end-to-end encrypted, so only invited users can see the content — Proton never has access to your data.

How easy is it to switch to Proton Pass from another password manager?

Switching to Proton Pass is easy and only takes a few minutes. The apps and browser extension include an import tool that supports vaults from popular managers like 1Password, Dashlane, LastPass, and major browsers. All you have to do is export your old vault and upload it to Proton Pass, and your logins will appear instantly. Most data carries over smoothly, though some advanced fields like 2FA codes require manual setup. Overall, Proton Pass makes the transition simple and beginner-friendly, so moving from another password manager isn’t a hassle.
