How to share Microsoft Ads access (Updated 2026)

If someone needs to work in Microsoft Ads, do not pass them the main credentials. The cleaner setup is to invite them as a user with their own login, or to use formal account linking when an agency is managing the account.

Based on Microsoft Advertising guidance, adding a user requires Super Admin access on the account. For agency work, Microsoft recommends a formal relationship instead of simply stacking more users into one account.

Step by step

1. Open Microsoft Advertising with a Super Admin account.
2. From Settings, open User management.
3. Choose Invite user.
4. Enter the invitation email and choose the account role.
5. Send the invitation and wait for the user to accept it.

Microsoft notes that the invitation email is mainly for sending the invite. The invited person can later sign in with a different Microsoft account if the setup allows it.

When to add a user and when to link an agency

• Add a user when it is an internal teammate or a named freelancer.
• Use formal account linking when a full agency account will manage campaigns.
• Keep billing and super-admin control on the client side wherever possible.

In practice, the same principle applies here as elsewhere: separate identity, intentional role choice, and fewer high-level permissions than feels comfortable at first.

If Microsoft Ads is only one part of the setup, the Sharing Access hub covers the rest.
