pCloud Pass uses client-side encryption: all data (passwords, payment cards, secure notes) is encrypted in the browser or app before upload, so that pCloud cannot see the plaintext information. The platform employs strong cryptography (AES-256 and elliptic-curve algorithms) and derives encryption keys from the user’s Master Password, which is never transmitted to servers. Users can create an unlimited number of entries (logins, credit cards, notes) under the free plan, with premium tiers adding features. The service offers browser extensions, desktop and mobile apps with features like password generation and autofill. As a “zero-knowledge” solution, pCloud Pass ensures all sensitive data remains private: only encrypted data is stored in pCloud’s infrastructure, and end users retain full control.
