Proton Pass, known for its secure password management, is expanding its functionality to compete with services like Google Wallet. The update introduces end-to-end encryption for a broader range of data, including custom information, identification documents, and more. This move enhances user privacy by ensuring that sensitive data stored within Proton Pass remains protected from unauthorized access, even by Proton itself. The expansion positions Proton Pass as a comprehensive secure vault for digital credentials and personal information.
