This involves scanning a QR code using an authenticator app, such as Google Authenticator, to link their account securely. Registration with 2FA Setup: When users sign up on our website, they're prompted to set up an extra layer of security-2FA.Here's a breakdown of the flow of two-factor authentication in our application: Two-Factor Authentication Workflow in Our Application Users can easily set up Google Authenticator on their devices to generate these time-sensitive codes, adding an extra level of security to their accounts. It functions as a secure platform for generating time-based OTPs, compatible with various services and applications supporting 2FA. Google Authenticator, on the other hand, stands out as one of the most widely used OTP generator apps available. This understanding will be beneficial as we get into the integration of PyOTP within your Flask application for Two-Factor Authentication (2FA). If you're new to PyOTP or would like a refresher on its functionalities, I recommend reviewing my previous guide on PyOTP. Its primary role revolves around creating these unique, time-sensitive codes that add an extra layer of security to user accounts.īy integrating PyOTP into your Flask application, you can easily implement Two-Factor Authentication (2FA) by generating and verifying these OTPs. PyOTP is a Python library that's incredibly handy for generating Time-based One-Time Passwords (TOTP) and HMAC-based One-Time Passwords (HOTP). Overview of PyOTP and Google Authenticator
