Managing Client Ad Accounts in One Dashboard: Multilogin for Agencies in 2025

Running ads for multiple clients in 2025 means more than just toggling between Meta accounts. Platforms now detect overlapping logins, mismatched devices, and proxy misuse — putting your ad accounts and client trust at risk.

If you’re managing 5, 10, or even 100 client accounts, using the same browser is a recipe for disaster. That’s why performance agencies are switching to Multilogin — the antidetect browser built for team collaboration, profile isolation, and agency-level scale.

The Problem with Traditional Browser Setups

Using Chrome profiles or browser switching tools creates several issues:

• Shared device fingerprints → Meta flags accounts
• No isolated session storage → Cookies and logins leak
• No access control → Junior staff may access sensitive clients
• Manual switching → Wasted time and increased error risk

Platforms like Facebook, Google Ads, and TikTok Ads detect these overlaps, leading to unexpected bans or disabled BMs.

How Multilogin Solves It for Agencies

🔒 1. Fully Isolated Profiles

Each client gets a dedicated fingerprinted profile — stored in encrypted cloud storage, ready to launch on demand.

👥 2. Team Collaboration Made Easy

Share access to profiles securely with account managers, interns, and freelancers. Control permissions and track changes.

🧠 3. Session Persistence

Profiles remember cookies, logins, and history — so you don’t need to log in again every time you relaunch.

🌐 4. Proxy + Fingerprint Matching

Assign residential or mobile proxies to each profile. Match timezone, language, and OS to client expectations.

⚙️ 5. API for Scaling

Use the Multilogin API to rotate profiles, launch automation tasks, or integrate into your agency’s internal CRM or ad toolchain.

Use Case: Managing 30 Client Ad Accounts Safely
