Does anyone know how can I hide from the form user the Kobo Account password?
Welcome back to the community, @basualdo! You will need to set an
admin password in your
KoBoCollect android app, which can be configured from Settings>Admin Settings>Admin Password.
You can do initial device configuration by Barcode, including hiding by admin password. Feel free to search in the community with “configuration Barcode”.
You should also separate on server level an KoBo admin and a user group account (or several).
