![]() Google authenticator login how to#Adding Two-Factor Authentication Now that we know more about how TOTP works, I’ll show you how to add it to the example application that we started with.Understanding TOTP Before I show you how to add TOTP to that example application, I’ll explain how TOTP works.An Example of Application I will start with a very basic Python application that implements password authentication and build from there.Here are the topics that I’ll be covering: The best way to see how this is done is to look at some code. This means that you only need to implement and test one additional authentication scheme, but get the benefits of having two different ways that your users can get tokens. What is so cool about TOTP is that it is flexible enough to allow your users to generate their authentication tokens directly on their smart phones using a TOTP app like Google Authenticator or have their tokens sent to their mobile phone via SMS. ![]() That device used to be a special-purpose device, but these days that device can just as well be a mobile phone.Ī great pattern that we are seeing for implementing two-factor authentication is to use the TOTP (Time-based One-time Password Algorithm) standard for the second authentication step. Google authenticator login code#Two-Factor Authentication is a method where your users are required to log in with two “factors”: a password, and a code from a device that they carry on their person. In the meantime, a simple and effective way of improving the way your users authenticate themselves is a method known as “ Two-Factor Authentication“, “Two-Factor Auth”, or just “TFA”. In an ideal world, we would all be authenticating ourselves using tamper-proof hardware that implements a public-key cryptographic system. Today, an attacker can discover your user’s password in a variety of ways: they might find your user’s password on a stolen or lost computer, they might find their password on another site where your user used the same password, or your user’s computer might be infected with a virus that is capturing their keystrokes. ![]() However, as the security landscape continues to evolve, it is becoming clear that a strong password policy is not enough any more. (Ah, those were the days, when kids were polite and respected their elders). Back in the day, it used to be that enforcing a strong password policy was sufficient to prevent unauthorized access into your user’s accounts. ![]()
