When a user try to login in my web site using "google social login" from an in-app browser as for example the facebook app in-app browser, the user received from google a page error: "403 disallowed_useragent".
This is perfectly legit, as written here: https://developers.googleblog.com/2020/08/guidance-for-our-effort-to-block-less-secure-browser-and-apps.html
Now, I don't want my user goes in that google page error and then I want to disable the social login buttons. What's the best control I can apply to disable buttons when we're in an app browser?
This solution does not work and is a completely differente case! First, the app is not mine and second, "FB in app browser" or "TikTok in app browser" for example, have not that type of user agent
