Anti-Detect Fingerprint Checklist

Q: How do I check for WebDriver leaks?

Inside the page context, verify navigator.webdriver is false and no automation-specific CDP artifacts are exposed.

Platforms detect automation through inconsistent or leaked browser fingerprints. Use this checklist before scaling Playwright, Selenium, or anti-detect profile fleets.

1. Canvas & WebGL consistency

Hash Canvas and WebGL output across two cold starts of the same profile. Drift between sessions is a common ban trigger. Tools like Multilogin manage preset fingerprints — compare against your custom spoofing if self-hosting.

2. AudioContext fingerprint

Advanced scripts probe AudioContext oscillators. Add controlled noise or use a managed anti-detect profile if your stack reads AudioContext signatures.

3. Timezone & locale alignment

Intl.DateTimeFormat timezone vs IP geo
navigator.language vs Accept-Language
Geolocation API vs proxy country

4. Automation leak signals

navigator.webdriver === true
Missing plugins / unrealistic hardware concurrency
Headless Chrome user-agent mismatches
CDP Runtime domain artifacts

5. Profile warm-up

Before high-value actions, simulate organic navigation: scroll, idle time, mouse movement. Log which step triggers blocks to isolate the detection layer.

6. When to use managed anti-detect

If audit items fail repeatedly, a platform like Multilogin handles fingerprint presets, proxy binding, and team isolation out of the box. Scripts via @Multilogin_Scripts_Bot.

FAQ

What causes Canvas fingerprint drift?

Inconsistent spoofing, GPU driver updates, or profile template changes between sessions. Same profile should produce stable hashes across relaunches.
