What Proton Pass is

The extension saves and autofills logins, generates passwords, stores 2FA codes, and creates hide-my-email aliases from an end-to-end encrypted vault that syncs across devices. Proton's free plan includes unlimited logins and devices with 10 aliases; paid plans add unlimited aliases, more storage, and family sharing.

Is Proton Pass safe to use?

Proton Pass is a safe choice by the public evidence: Proton documents end-to-end encryption on all vault fields, says its apps are open source and independently audited, and the extension is actively maintained with a large user base. Like every password manager it needs broad autofill access, so protect the account with 2FA.

Page access Broad

Requests page-content access across sites. Broad access is not itself a red flag — the question is whether the job justifies the reach, and whether the publisher's record earns it.

Autofill and login capture need to read and fill form fields on any site where you sign in, which is why the extension asks for broad site access. Chrome's site-access setting can switch it to on-click, at the cost of automatic fill suggestions when a login page loads.

Store-disclosed data

  • Authentication information
  • User activity
  • Website content

The listing names authentication information, user activity, and website content as handled data. Proton says Pass applies end-to-end encryption to every vault field, including usernames and web addresses, so synced vault contents are not readable by Proton. Proton AG runs the service under Swiss law, per its privacy policy.

Can Proton see the passwords stored in Proton Pass?

Proton says no. It describes end-to-end encryption on all vault fields, including usernames and web addresses, and its privacy policy says it lacks the technical means to read encrypted passwords or notes. The listing still discloses authentication information because handling credentials is the product's job.

Is Proton Pass really free?

Yes. Proton's pricing page lists a free plan with unlimited logins, notes, and devices, 10 email aliases, and 2 vaults. Pass Plus, Pass Family, and Proton Unlimited add unlimited aliases, more storage, and sharing features.

Why does Proton Pass need access to all websites?

To detect login forms and fill credentials wherever you sign in. Restricting it to on-click in Chrome's extension settings narrows that access but removes automatic fill prompts.
