Because of recent changes to App Store Connect user authentication, older methods of signing in with Sensor Tower are no longer allowed. As Apple changes their rules, we will roll out new ways to connect your App Store Connect account to Sensor Tower.
Currently, there are two supported methods for authentication:
1) We recommend creating a new Apple ID, giving that account the Finance Role in your Apple Developer account, and signing in to Sensor Tower using that Apple ID. Those instructions are available here.
2) Alternatively, we also support signing in with your existing Apple ID and completing two-factor or two-step sign in. Additionally, if you change your Apple ID password at any time in the future, all app-specific passwords will be revoked, and you’ll have to reconnect Sensor Tower. Those instructions are available here.
