If others will be managing your campaigns with you, we recommend adding them to your account as an additional user rather than sharing a login. This minimizes the need to share passwords by email (don't do it!!) and also allows for better event logging, which can be useful in case a change is made that you did not authorize.
Give an Additional User Account Access
Navigate to Settings > Users Permissions.
Enter the email address you would like to add.
Determine the level of access you wish to provide to the user being added. Under User Role, specify either General User or Administrator.
Under Profile Access, the profiles that the user can access, or select All Advertiser Profiles to provide full access.
(Optional) If needed, General Users can also be granted access to billing tools. Note: Administrators are automatically provided with this level of access.
Setting a user role as either Administrator or General User will determine their access level.
Administrators have the same access as the main account holder, including the ability to manage billing and additional users on the account.
Adding a General User allows you to have greater control over access to specific profiles and to billing, as needed. When provided with full access, a General User can perform all the functions that an Administrator can, except for managing additional users on the account.
