mOTP is an open source, two-factor authentication service. It uses a missed call rather than SMS to send users a One Time Password (OTP) for use in two-factor authentication. This allows users to side-step the costs and delays that can be associated with SMS, which is used in most other two-factor authentication services. Developers can integrate mOTP into their own applications or web-based services using REST calls.
The following is a list of sample source code snippets that matched your search term. Source code snippets are chunks of source code that were found out on the Web that you can cut and paste into your own source code. Whereas most of the sample source code we've curated for our directory is for consuming APIs, we occasionally find something interesting on the API provider side of things. If you know of some sample source code that would be of interest to the ProgrammableWeb community, we'd like to know about it.
