Hello, Hope you are doing well For generates one-time passwords using the OTP algorithm using the Google Authenticator project includes implementations of one-time passcode generators for several mobile platforms. One-time passcodes are generated using open standards developed by the Initiative for Open Authentication (OATH) (which is unrelated to OAuth. These apps are not on the app stores, and their code has diverged from what's in the app stores, so patches here won't necessarily show up in those versions. These implementations support the HMAC-Based One-time Password (HOTP) algorithm specified in RFC 4226 and the Time-based One-time Password (TOTP) algorithm specified in RFC 6238. Another method for OTP generator OTP has three major functionalities: OTP provisioning, OTP generation, and OTP verification. There are also APIs for querying OTP capability and the OTP version on the system. InvokeIPTProv extends the AsyncTask to execute the provisioning in the background. It first creates the security service (Provision Service) and then starts the provisioning process if you have any query please have, I ready to explain my work Thanks
