Mobile Authenticator Studio supports the input of user credentials for online activation requests as an image, either as a QR code or a Cronto image.

The content of the image must be generated using the Secure Messaging SDK Server 4.6.1 or later by calling the credential message generation functionality.

Java

publicstatic String generateCredentialsMessage(String registrationIdentifier, String authorizationCode, String activationPassword, String userIdentifier) throws MessageSDKException

.NET

publicstatic String GenerateCredentialsMessage(String registrationIdentifier, String authorizationCode, String activationPassword, String userIdentifier)

The image can be generated using the Image Generator SDK 4.3.5 or later by calling either the QR code generation API or the Cronto image API.

Java

publicstatic BWQRCodeResponse generateBWQRCode(int imageSize, String inputValue, int errorCorrectionLevel) throws ImageGeneratorException

publicstatic BufferedImage generateCrontoSign(int squareSize, String inputValue) throws ImageGeneratorSDKException

.NET

publicstatic BWQRCodeResponse GenerateBWQRCode(int imageSize, String inputValue, int errorCorrectionLevel)

publicstatic Bitmap GenerateCrontoSign(int squareSize, String inputValue)
