What is passwordboss-syncservice.exe?
passwordboss-syncservice.exe is the background Windows service that powers Password Boss synchronization. It runs continuously to propagate vault changes, apply encrypted updates, and keep passwords in sync across your devices even when the app isn't actively open.
This service operates in its own process to handle vault synchronization, conflict resolution, and incremental updates. It communicates securely with Password Boss servers, verifies data integrity, and ensures multi-device consistency even when the main UI isn't active.
Quick Fact: Password Boss Sync Service uses TLS for data in transit and AES-256 for vault encryption, running as a separate process to improve reliability and security.

- Worker Threads: Background threads performing encryption, change detection, and conflict resolution
- Update Process: Module that handles auto-updates and signature verification
- Security Module: Cryptographic operations for vault encryption/decryption
- Event Listener: Listens for vault changes and triggers sync tasks
