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.

One workspace across six platforms

Meta, Google, TikTok, Taboola, Snapchat, and Outbrain all live in the same portfolio view. Switch between clients instantly, with no logging in and out and no tab sprawl.

Bulk launch at portfolio scale

Filter across accounts, then launch, pause, and duplicate campaigns across hundreds of accounts at once. Portfolio-wide operations that used to take a day take minutes.

What changes when access is a role, not a password

connect the whole portfolio, no per-account logins

One-click revoke

remove a buyer without touching any Business Manager

Full audit trail

a clean record of who did what, per account

Zero credential sprawl

7 Permission Mistakes That Put Your Clients' Ad Accounts at Risk

Most agency security problems are not attacks. They are permission mistakes that compound silently: shared logins, over-granted analysts, account-wide access. Here are seven, and the role-based fix for each.

Shared Logins Are Quietly Killing Your Ad Agency: The Case for Role-Based Seats

One shared password felt efficient at three clients. At thirty, it is operational debt: no accountability, no security, no defensible record. Here is how seven scoped permission tiers replace the shared login for good.
