First Setup: Create Your Isolated Browser Environment

Inside the MostLogin client, click “New Browser” to create your first virtual profile.

Configuration Tips:

• Name: Use something meaningful like “Facebook Account 01” or “Amazon Store 02”
• Tags: Use for searching and organizing later
• Groups: Organize by platform, region, or business use

Click “Next” to begin fingerprint configuration.

Fingerprint Settings: Build a Truly Isolated Profile

MostLogin auto-generates a browser fingerprint for each profile, or you can customize it manually:

• Operating system (Windows/macOS/Linux)
• Screen resolution, language, timezone
• Canvas/WebGL/fingerprint fonts, hardware memory
• WebRTC, audio context spoofing, and more

Pro Tip: Use the recommended defaults for better anonymity and account safety.

Network Settings: Set Up Independent Proxy Connections

In the “Network Settings” tab, assign a dedicated proxy to each browser container.

Supported Protocols:

• HTTP / HTTPS
• SOCKS5
• Static residential or dynamic rotating proxies

Format Examples:

• IP:Port
• IP:Port:Username:Password (for authenticated proxies)

Test the connection before saving. A unique proxy per profile helps prevent IP-related account bans.

MostLogin supports a full-featured team management system, allowing multiple users to collaborate without cross-contamination.

• Create teams and invite members by email
• Assign view/edit permissions for each user
• Keep operation logs to track changes and ensure accountability
• Sync browser profiles across devices via cloud storage

Perfect for mid-to-large teams managing dozens or hundreds of accounts.

MostLogin is more than a browser—it’s the foundation for building secure, scalable, and compliant account operations.
