How to get Google Authenticator pass code into our android app without swap the app and manual entering when enable Two-Factor Authentication to my developed app
Twilio developer evangelist here.
I know it's not Google Authenticator, but I do have a product that you can use to get a frictionless 2 factor authentication process without making your user copy the digits across to your application.
Twilio two factor authentication offers what we call OneTouch. It sends a push notification to the Authy app which the user can then approve or deny within the application and carry on using your app.
As far as I know, you cannot achieve this with Google Authenticator.
