The Onegini Mobile Security Platform offers an ability of mobile authentication with a One Time Password (OTP). Mobile authentication with OTP provides users an easy and secure way for two factor authentication or single factor authentication where no passwords are required. A good use case is for example letting a user login to your web application using his/her mobile device by scanning a QR code displayed within a browser. This essentially allows the user to authenticate using his/her mobile device. All of the communication stays between App, web application and Mobile Security Platform.
