The Challenge

Every new client is another login to guard

This is what managing dozens of client accounts on shared credentials really looks like.

A new credential for every account

Each new client means another Meta login, another tab, another password and 2FA seed to rotate. Onboarding stalls while you chase access, and your team drowns in context-switching before any work gets done.

Shared passwords are a security and audit nightmare

Handing buyers raw logins and 2FA seeds means anyone can see anything, juniors can touch live campaigns, and you have no clean record of who changed what. One leaked credential is one client incident away.

Off-boarding means hunting access everywhere

When a buyer leaves you spend days combing through dozens of Business Managers to revoke access, never quite sure you got it all. Credential sprawl turns a routine departure into a security exercise.

The Solution

Connect once, control the whole portfolio

Enter a System-User token a single time. Wevion auto-discovers every Business Manager and account, then lets you assign buyers through internal roles, so nobody ever holds a Meta credential and everything across six platforms lives in one workspace.

One System-User token, full auto-discovery

Enter the token once and business_id auto-discovery surfaces every Business Manager and ad account it can reach. No account-by-account invitations, no credential collection, no missed accounts.

Internal RBAC instead of Meta logins

Assign buyers to accounts and roles inside Wevion. They operate on exactly what you grant, and never touch a raw Meta login, password, or 2FA seed. Access is a setting, not a secret.
