Undetectable.io Issues That Caused Mass Account Bans — My Real Experience

In the ever-evolving world of antidetect browsers, Undetectable.io is a name that’s been gaining attention. Promoted as an affordable, easy-to-use solution with strong fingerprint protection, it sounded perfect for managing multiple ad accounts. But after testing it in real-world campaigns, I experienced serious problems — including mass account bans. Here’s my honest experience, and the solution I now rely on.

Why I Tried Undetectable.io

I manage large-scale Facebook Ads, TikTok Ads, and Google Ads campaigns. I was looking for an antidetect browser that could:

• Provide strong fingerprint spoofing
• Support automation (important for scaling)
• Offer an affordable subscription for large teams
• Be easy to set up and manage profiles

Undetectable.io ticked all the boxes on paper, so I purchased a subscription and migrated 40 ad profiles to test it.

Issues That Caused Mass Account Bans

1️⃣ Incomplete Fingerprint Spoofing

While Undetectable.io markets itself as having strong fingerprinting tech, my testing told a different story. Many of its fingerprint profiles failed advanced WebGL, Canvas, and AudioContext tests. Platforms like Facebook and Google detected inconsistencies quickly.

2️⃣ Repetitive Fingerprints Across Profiles

Even though I configured different profiles with different proxies, several had identical or near-identical fingerprints. This led to account linkages and mass bans across multiple profiles.

3️⃣ Poor Automation Support

The platform claims to support automation, but in reality, it was buggy and unreliable. Running automated posting and warm-up scripts led to profile crashes and forced logouts.

4️⃣ Profile Instability

Undetectable.io updates frequently broke profiles. After an update, several of my profiles became corrupted — I lost valuable account sessions that couldn’t be restored.

5️⃣ Increased Detection Over Time

Initially, results seemed okay. But after two weeks, detection rates shot up. Platforms appeared to adapt to Undetectable.io’s fingerprint patterns, and bans began rolling in across my test accounts.

The Browser That Fixed It — Multilogin

After losing several valuable ad accounts and seeing my team’s efforts wasted, I needed a proven antidetect browser. Trusted contacts strongly recommended Multilogin, and after testing it, I fully understand why.

Benefits I experienced with Multilogin:

• Fingerprint profiles pass all advanced tests (Canvas, WebGL, AudioContext, more)
• Truly unique fingerprints across all profiles
• Excellent automation support — integrates with my scripts perfectly
• Highly stable profiles that don’t break after updates
• Very low detection rates — my bans dropped dramatically after switching

Multilogin also offers a Free Trial and a 50% discount (use code: ADBNEW50), making it easy to test risk-free. After switching, my account survival rates improved massively, and campaign scaling became predictable again.

Final Thoughts

Undetectable.io may be fine for basic testing or light use. But for serious ad scaling and long-term account health, it simply isn’t robust enough. Multilogin delivers the fingerprinting strength, stability, and automation support required for real business use.

If you’re managing valuable ad accounts or running serious campaigns, don’t risk mass bans. Start with Multilogin — it saved my campaigns, and it can save yours too.
