To change which account your app is attached to:
Android: Long press on the ClearToken® app's icon, then select "Clear Data". When you next open the app, it will ask for your cell phone number.
iOS: Uninstall the app by
Going to Settings
-> General
-> iPhone Storage
-> Find our app in that list
-> Uninstall the app and answer the question "Do you want to clear the data and app storage?" with "Yes"
-> Reinstall the app and accept all permissions.
When you next open the app, it will ask for your cell phone number.
