Since version 2.0.8, the RapID app will only ask you for your PIN or fingerprint once when you first use it until you exit the app. On Android it is important to realise that the ‘Back’ button does exit the app, whereas the ‘Home’ button just swaps to your desktop without exiting. So, if you want to keep the app alive to avoid re-entering your fingerprint or PIN for each site you login to, use the Home ( O ) button rather than Back ( <| ) to leave it running in the background.
