How can I implement multi-factor authentication in Firebase with TypeScript?

To implement MFA in Firebase with TypeScript, you can use Firebase Authentication's built-in support for multi-factor authentication. First, ensure you have Firebase set up in your TypeScript project.

What are the steps to enable MFA in my Firebase project?

You need to enable MFA in the Firebase console, then configure your authentication methods. After that, you can use the Firebase SDK to handle the MFA flow in your TypeScript code.

Can you provide a code example for sending a verification code?

Sure! You can use the firebase.auth().currentUser.sendEmailVerification() method to send a verification email. For SMS, use firebase.auth().signInWithPhoneNumber(). Here's a sample code snippet.

What if the user doesn't receive the verification code?

If the user doesn't receive the code, ensure that the phone number is correct and that the SMS service is properly configured in your Firebase project. You can also implement a resend code feature.
