Edge's native password features provide basic credential storage, yet enterprise-grade security demands more robust protection.

Psono generates provably random passwords using cryptographic algorithms for each service, implements NaCl encryption locally before any storage occurs, and offers configurable multi-factor authentication for vault protection. The Edge extension delivers native toolbar integration for rapid credential access while preserving encryption integrity during both storage operations and cross-device synchronization.
