Google Authenticator TOTP C# 1891 An implementation of Google's Authenticator in C# and WPF. It's a Time-based One-time Password (TOTP) described in RFC 6238. If you want to implement this yourself (which I can highly recommend if you are doing this just for fun) you can use the following HMAC implementations that are already part of System.Security.Cryptography: HMACSHA1 (default), HMACSHA256, HMACSHA512 and HMACMD5. Google Authenticator OpenSource The Google Authenticator project includes implementations of one-time passcode generators for several mobile platforms. One-time passcodes are generated using open standards developed by the Initiative for Open Authentication (OATH) (which is unrelated to OAuth ). Google Authenticator offers an easy way to use time based one time passwords (TOPT) using Google infrastructure and mobile apps.

TOTP (Time-based One Time Password) is the mechanism that Google Authenticator, Authy and other two-factor authentication apps use to generate short-lived authentication codes. We’ve written previously on the blog about how TOTP works.

Continue with your Google account setup and enter the code that WinAuth gives you. Copy the generated one-time password and paste it to your Google security settings page and click on the button “Verify and Save” to verify the generated code.

TOTP drives Google Authenticator and many other compatible systems. To make TOTP work with time, the counter is defined as the number of intervals that have passed since a reference point in time. Google-Authenticator-compatible TOTP systems standardized on thirty-second intervals and the Unix epoch.

It's a Time-based One-time Password (TOTP) described in RFC 6238. For added security, you can also set up Time based OTP (TOTP) in place of Kite PIN. You can use apps like Google® Authenticator, Microsoft® Authenticator, or Authy on your mobile phone or PC to generate 6-digit TOTPs for every login.

Google Authenticator offers an easy way to use time based one time passwords (TOPT) using Google infrastructure and mobile apps. The authentication module can be used by itself or in combination with other authentication modules for multi-factor authentication. A new verification code is automatically generated every thirty seconds. The algorithm for TOTP is defined in RFC 6238, which means that the open standard can be implemented in a compatible way in multiple applications. You might be familiar with TOTP from apps like Authy or Google Authenticator, but there are a lot of other options including Duo and Microsoft Authenticator.

Google Authenticator uses a default value of 30 seconds, which can NOT be modified according to the documentation provided. This causes different codes to be generated by both TOTP computations resulting in an always false authentication.
