Why Advertising Agencies Rely on Multilogin to Manage Multi-Client Accounts Securely

Introduction

Modern advertising agencies are expected to juggle dozens of client accounts across platforms like Facebook, Google, TikTok, and Instagram. Each account has different budgets, target audiences, and platform histories.

But there’s one problem most agencies struggle with: running multi-client campaigns without triggering bans, flagging IP mismatches, or losing access to ad accounts.

That’s where Multilogin becomes a game-changer.

Problem: One Mistake Can Get All Your Clients Banned

Without browser isolation or fingerprint protection, most ad agencies run all campaigns from a single computer or centralized IP. This creates major risks:

• Platform bans due to similar browser fingerprints
• Cross-contamination of cookies and sessions
• Facebook Business Manager flagging account links
• Delays due to constant 2FA and login issues
• Inability to scale efficiently across team members

A single browser login mistake can risk every client’s trust and campaign budget.

Solution: Multilogin Enables Safe, Isolated Advertising Environments

Multilogin allows advertising teams to create fully isolated browser profiles—each one simulating a different device and IP.

Each browser profile includes:

• Unique fingerprint (OS, fonts, canvas, resolution)
• Assigned proxy (residential/mobile)
• Saved cookies and ad account sessions
• Session storage and login persistence
• Ability to share profiles securely with other team members

You can run 5, 50, or even 500 client accounts — all without triggering suspicion or bans from Facebook, TikTok, or Google.

Use Case: A Boutique Agency Running 20 Facebook Ad Accounts

Let’s say your agency handles:

• 7 ecommerce clients
• 5 service providers
• 8 coaches/influencers

All want aggressive ad scaling, but Facebook flags:

• Too many logins from same location
• Inconsistent browser history
• Cross-profile cookie interference

With Multilogin:

• You create 20 unique browser profiles
• Assign a clean IP (proxy) to each based on target country
• Save Facebook sessions and tokens
• Distribute workload to your ad buyers via cloud sharing

This lets you scale spend without suspensions — and keep every client happy.

Tips for Agencies Using Multilogin

1. Use separate proxies per client
   Never reuse proxies across different ad accounts.
2. Label browser profiles clearly
   Include client name, budget size, platform (e.g., Nike_US_Facebook_LeadGen).
3. Automate backup of each profile
   Use cloud sync or schedule offline exports.
4. Avoid opening same profile twice
   Assign dedicated users or schedule usage.
5. Combine with tracker or CRM tools
   Like Hyros, GoHighLevel, or agency dashboards to centralize reporting.

• Simulate individual devices
