The Mobile Authenticator Studio app can be configured to display an end user license agreement (EULA) after the app has been installed. The user must accept the terms. If they do not accept them, regardless if they tap Decline, or tap OK and close the app and/or restart the device, the app cannot be activated and used.
The user will be prompted to accept the terms until they actually complete this action. This is a one-time agreement, as soon as the user has accepted the terms, the EULA will not be displayed anymore, even when you update to a new version of Mobile Authenticator Studio.
Mobile Authenticator Studio provides multi-lingual support and enables you to display the EULA in the languages you want to use in your project.
