Last Friday Wechat opened up internal testing of Wechat Login API for apps and websites to those who have already activated mobile app Wechat Payment account.
With permissions from users, app and website owners can also retrieve users’ basic information such as profile photo, nickname, gender, location and language.
Tencent has already been providing API for developers to integrate QQ Login which also has huge user base. In comparison, user info retrieved via Wechat Login are more real. Another benefit of using Wechat Login is the integration and convenience of Wechat Payment.
