I need a Two-Factor Authentication Android App Locker

I need a android app just like a normal android app locker in playstore. but there's one small change. Normal app locker have only pin or pattern, it's a single factor authentication but in my app i want double factor authentication which means i need (pin or pattern) + security question & answers.

About my app:-

I want a external app locker which has 2 factor authentication to lock/unlock the apps in my mobile which are pin and security questions. the app wants to lock the external apps in my mobile when the user tries to open the locked app then it shows prompt or overlay to enter the pin and security questions at a same time. If user enters both pin and security correctly then allow the users to enter the locked apps which is unlocked.

App working & Activity's :-

When the user installed my app first time the app asks to setup pin and security questions. when user enters the details then the app should store the entered details and moves to another activity which shows the app list to asks the user which are the apps the user wants to lock and unlock. when the user chooses or selected which are apps should be lock/unlock then the app should locks/unlocks those apps which was selected by the user. when the user open the locked apps in his mobile it asks the pin and security questions which was entered and stored by the user in the created app. when the user enters correct pin and security questions then that app should unlock. so I want the app with proper working conditions with frontend and backend. use any third party to make this app. I want pin, security questions only.


App name is : thfa
Package name is : com.msn.thfa


For example : in this app the user setup their pin and security questions for the first time and the user selects which apps he wants to lock in the app list (eg. youtube). And then the user exit this app and opens youtube the device asks the pin and security questions to open the youtube.
Note : I need a full integrated working app.

i hope you understand if you have any doubt contact me.
I need this app as quick as possible within 3 to 5 days
