To share your account details you must first locate the Settings. This can be found in the top right corner of your Xonder App screen. From there, you will want to click the first option labelled Account Information. Once you are on the Account Information page, at the bottom of the screen you will see a button which says Share Account Details. If you click that, your mobile device should compile a list of apps for you to carry out this action with. It is then your choice which you choose, and whether or not you want that application to be used every time you need to share your account details, or just this once.
