What is Proton Pass?
Proton Pass is a free password manager from Proton, the Swiss company best known for Proton Mail. It stores logins, secure notes, and file attachments using zero-knowledge, end-to-end encryption, which means your data is encrypted on your device before it ever reaches Proton's servers. The practical result is that nobody outside your own head, not even Proton's staff, can read what is inside your vault.
Combined with apps that work across phones, laptops, and browsers, it aims to make strong security feel like less work, not more.
Proton Pass is a cross-platform password manager that keeps your online credentials, sensitive notes, and attached files in one encrypted vault. It is built on the same zero-knowledge architecture that protects millions of Proton Mail accounts: encryption happens on your device, and decryption keys are never available to Proton's servers. You can use it on mobile, desktop, or directly in a browser, and entries stay synchronized through your encrypted account.
It is offered free of charge, with Proton positioning it as a privacy-respecting alternative to password managers funded by advertising or data monetization.
