In the Users section of the AppLovin dashboard you can add users to your account and give them a variety of access options across MAX and Axon’s Ads Manager. You can also perform general account administration.
You can give users full access to your account or you can limit their access to reporting, ad management, and payment information. You can do this across all your apps or for particular ones.
To add a new user:
The new user can return to the UI and update their password if they desire.

You can associate an email address with only one account. You cannot add an account that uses an email address that is associated with an existing account.
