Steps to add Multi-Factor Authentication to a Payment Gateway

There are different types of two-factor authentication that can be implemented:
SMS-based Authentication: A one-time passcode (OTP) sent to the user’s mobile number.
Email-based Authentication: A unique code is sent to the user's registered email address.
App-based Authentication: Using apps like Google Authenticator, Authy, or Microsoft Authenticator to generate time-based, one-time passcodes (TOTP).
Biometric Authentication: Fingerprints or facial recognition via mobile devices.
Push Notifications: Push notifications are sent to the user’s device, asking for confirmation of the transaction.
