To change your passcode is very simple, just follow the next few steps:

1. First head over to the Settings page which can be found by clicking the icon in the top right corner of the Xonder App screen.
2. Once there, click the fifth option down which reads Change Passcode.
3. Here you will not be required to enter your old passcode, you will only need to type in what you want your new passcode to be.
4. You will then need to retype out your new passcode to confirm it is correct and the passcode you are sure you want to change it to.
5. After that, just click Save Changes at the bottom of the screen and then your passcode will be updated.
