In response to changes in Google's OAuth policy, which will block OAuth requests through the InAppBrowser plugin starting October 20, 2016, developers are encouraged to use the Google Sign-in Plugin with Ionic Native for a more secure and improved sign-in experience. The transition involves setting up a Google Developer account, obtaining necessary credentials, and installing the appropriate plugin from GitHub. The article provides a brief guide on implementing this setup in Ionic apps, offering code snippets to facilitate user authentication through Google. While most instructions focus on Ionic 2, the guide assures developers using Ionic 1 that similar implementations can be achieved with minor adjustments. Despite the initial perception of the policy change as challenging, the transition is presented as straightforward, with minimal code adjustments required, and support for this change is also being integrated into Ionic Cloud’s Auth features.
