Google authenticator totp mode vs hotp3/12/2024 ![]() If you also enjoy visual learning, here's a fancy video showing how the app does its thing. This seamless back-and-forth between passwords, authenticator apps, and unique codes ensures that only the rightful account owner can access the precious content behind the digital doors of your website. If the OTP matches, it's like handing over the secret handshake, granting the user access to their account. The system then double-checks this OTP against the expected code, validating the information. Validation and Authorization: The user inputs the received OTP into our platform.This ensures they're not just entering the password but also confirming their identity with a unique, time-sensitive code. Extra Security Check: Before granting access, our website throws in an additional hurdle: users need to provide an OTP (One-Time Password) displayed on their authenticator app.Login Initiation: When users return to log in, they start by entering their usual email/username and password combo to access their account.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 How to Run the Completed App for the First Time.How to Create Blueprints for Accounts and Core.Two-Factor Authentication Workflow in Our Application.Overview of PyOTP and Google Authenticator.So, let's explore how to set up this extra layer of protection using PyOTP and Google Authenticator in your Flask app. It's an extra step that makes your accounts much harder for hackers to break into. Passwords can sometimes be guessed or stolen, but with 2FA, even if someone gets your password, they'd still need that extra code or device to get in. Think of it as a shield for your accounts. ![]() It's a bit like needing both a key and a special code to open a vault. Instead of just using a password, 2FA adds another layer of security. Two-Factor Authentication, or 2FA, is like having an extra lock on the door to your online accounts.
