Instagram error: Implicit authentication is disabled

Question

When try to login to my app with Instagram account in mobile Safari I get 403 error: Implicit authentication is disabled.

Answer 1

By security reasons Instagram disables OAuth 2.0 implicit authentication flow (client-side authentication) by default. If your app hasn't server side you should go to Manage Clients Security section and unset Disable implicit OAuth option. After saving all should work well.
