LoginRadius is a service that allows users to log in to multiple websites with their existing social network accounts, such as Facebook and Twitter. Companies can integrate LoginRadius into their websites to allow their visitors to log in with their social network accounts.
The LoginRadius API allows developers to access and integrate the functionality of LoginRadius with other applications and websites. Some example API methods include authenticating sessions, managing user accounts and data, and retrieving user data. Documentation is available with an account and login.
