Open the pasby™-app and follow this steps:

1. Select "Settings" in the bottom navigation bar.

2. Underneath active pass select "Change security code".

3. Choose a new, 6-16 digit pasby code that only you know.

Did you forget your pasby code?

Then you need to block/deactivate your pasby for that device and then activate a new one. You can also do this by deleting your pasby™-app, reinstalling it via the Apple app store or Google Play store and activating a new pasby™.
