How Agencies Use Multilogin to Manage Multiple Client Ad Accounts Safely

Introduction: Agency Growth Without the Risk

If you’re a performance marketing agency or freelance media buyer managing:

• Multiple Facebook Business Managers
• Separate Google Ads accounts
• TikTok or Snapchat Ads for different brands
• Native traffic platforms like Taboola or Outbrain

…you know the pain of getting accounts linked, flagged, or even banned due to:

• IP overlap
• Browser fingerprint reuse
• Cookie bleed
• Shared login environments

Multilogin solves all of this with secure, isolated browser containers that make each client account truly independent.

Why Ad Platforms Flag Agencies Managing Multiple Accounts

Platforms track everything:

Even if you’re operating legally, these overlaps can cripple an agency with suspended accounts and delayed campaigns.

How Multilogin Helps Agencies Scale Ads Safely

✅ 1. One Profile Per Client = Total Separation

Each Multilogin profile is:

• Fingerprint-isolated (canvas, WebGL, audio, fonts)
• IP-isolated (dedicated proxy per client or campaign)
• Session-persistent (stay logged in without reauth)
• Cookie-contained (no cross-tracking or cache leak)

You can:

• Assign a separate browser profile for each brand/client
• Easily switch between campaigns
• Protect client privacy and ad performance

✅ 2. Onboard Team Members Without Exposing Credentials

Managing campaigns with:

• Freelancers
• VAs
• Designers
• Ad buyers

…becomes safer by exporting .mlb profiles.

Each collaborator gets:

• A pre-authenticated environment
• No password sharing
• No fingerprint contamination
• Immediate access to client dashboards

✅ 3. Prevent Account Linking Across Platforms

Many agencies get banned on:

• Facebook → when using multiple BMs from one IP
• TikTok Ads → due to reused fingerprint
• Google Ads → when testing MCCs without proper separation

Multilogin stops this by making each account appear from a unique browser and device, complete with:

• Proxy per client
• Local timezone/language
• Isolated storage

✅ 4. Track Results and Build SOPs per Client

You can tag profiles with:

• client-name-fbads
• client2-gads-remarketing
• client3-native-taboola

…and create SOPs for:

• Daily optimization
• Ad approvals
• Funnel testing
• Pixel/fire verification

Everything is structured, secure, and recoverable.

Use Case: Scaling a 12-Client Paid Ads Agency

Before:

• Agency uses Chrome + Meta profiles
• VAs login via VPN
• 3 BMs get disabled due to login mismatch

After:

• Each client = 1 Multilogin profile
• Each VA gets assigned .mlb files
• 0 bans in 4 months, higher client trust

Bonus: internal SOPs for profile tagging and backup reduce onboarding time by 60%.

Use Case: White-Label Facebook Ads for Local Businesses

A white-label partner runs ads for:

• 5 local businesses using their own BMs
• Different IP ranges, languages, and ad policies

Using Multilogin:

• Creates 5 browser profiles with regional proxies
• Maintains separate logins and ad creatives
• Avoids Meta cross-account review bans

Result: Consistent ROAS and no disruption from bans.
