Implement android app to get TOTP codes internally without using Microsoft Authenticator app

Mohamed Ahmed 1

Hi,

I'm developing an android application and using Microsoft Azure Active Directory B2C to make the user flow authentications of sign-in.
I enabled the 2FA and I don't want to use the Microsoft Authenticator app to get the TOTP I want to get this code through my android app.
My application will be two screens, the first one is for login (insert email & password) and if it's valid, it navigates to the second screen which has the TOTP code for this user and I want to be able to regenerate it after getting expired.

So, I need to develop the functionality of the Microsoft Authenticator app for getting the TOTP codes internally with my app, Is it possible to do something like this?

Thank you in advance!

Best regards,
Mohamed

@Mohamed Ahmed Thank you for reaching out to us. Let me check with my team if it is feasible or not to develop the functionality of the Microsoft Authenticator app for getting the TOTP codes internally within your app.

@Mohamed Ahmed Apologies for the delay, As I understand you are looking for logic similar to Authenticator app to generate TOTP codes within your app and same needs to be integrated with Azure AD B2C ( correct me if am wrong ), researched on the same couldnt find the logic/sample on how to create TOTP codes within your own android app.

However you use Azure AD B2C MFA with TOTP using any Authenticator app supports the TOTP protocol. ( Reference: https://github.com/azure-ad-b2c/samples/tree/master/policies/totp )
