Why Upwork Has Strict Security Checks

Upwork monitors account environments closely to prevent fraud and abuse. It checks:
- IP Address: Frequent IP changes or data center proxies trigger risk control.
- Browser Fingerprints: Includes User-Agent, Canvas, WebGL, timezone, language, etc.
- Device Consistency: Logging multiple accounts on the same device may lead to linking.
To succeed on Upwork, your account environment must appear unique and authentic.
