What are the different PINs and passwords for?

You can have up to 6 keys when working with Fully:

• The Kiosk Mode PIN set in the Fully Kiosk app is needed to get out from the Kiosk Mode. Default PIN is 1234. If the PIN is empty the PIN dialog will be omitted. If you forget the Kiosk Mode PIN check this FAQ how to exit.
• The Wifi/Settings PIN set in the Fully app only allows to access Wifi or other Android Settings in Kiosk Mode. You can give this PIN to someone who is only allowed to manage Wifi or other connections/settings but may not change anything else on the device or in Fully Kiosk settings.
• The Remote Admin Password is set in the Fully Kiosk app settings on each device. You need this Password to login to Remote Admin interface locally at http://ipaddress:2323/ or use the REST API. When adding device to your Fully Cloud Account you have to specify this Password in order to allow Fully Cloud talking to the device. If this Password is not set in the Fully app or you forget it you can’t connect locally to Remote Admin interface and you can’t add this device to the Fully Cloud.
• The Fully Cloud Account Password is used with your email to login to Fully Cloud. If you forget the Fully Cloud Password you can make Password recovery with your email address.
• The Fully Cloud API Access Token is needed for using Fully Cloud REST API. This token can be grabbed in Fully Cloud Settings.
• The Fully PLUS Volume License Key is a secret key sent to you when you order a volume license. You can activate a PLUS license for current device by entering this key in Fully’s Other Settings. You can also add all devices activated by the specified Volume Key to the Fully Cloud account at once.

You can change the Kiosk Mode PIN, the Wifi PIN, the Remote Admin Password and the Volume License Key via Remote Admin interface (locally or in Fully Cloud) in View/Edit Settings. For security reasons you cannot change the Remote Admin Password by importing a setting file via Remote Admin.
