Warning: sharing your TOTP seed with third-parties breaks the very basic assumption of multi-factor authentication that the TOTP seed is secret . So, I'm aware of the documentation on this, found here: Google Authenticator Key URI Format When I follow this example from that page: otpauth://totp/Example:alice@google.com?secret=JBSWY3DPEHPK3PXP&issuer=Example And I 'splice' it into a Google Charts URL, thus: https://www.google.com/chart?chs=200x200&chld=M|0&cht=qr&chl=otpauth://totp/Example:alice@google.com?secret=JBSWY3DPEHPK3PXP&issuer=Example It will display a valid QR code, and if I scan it

I'm looking for a tutorial on how to use Google Authenticator in .NET-apps. Does this exist, and if so, where can I find it? I understand that this can be used to add two-factor-authentication to your own apps. While playing around with Google Authenticator, I came across this question and in particular the code contributed by Espo. I personally wasn't satisfied with the conversion from Java to C# and so I thought I would share my version. Aside from heavily refactoring the code: Introduced check for little-endian byte ordering and convert to big-endian as necessary. Introduced parameter for

现在很多团队都在使用 jumpserver（ http://www.jumpserver.org/ ）作为跳板机，管理服务器权限，一些对安全要求比较高的团队还会加上 Google authenticator （Google 身份验证器）。 但是安全和方便就是跷跷板的两端，太安全了，就会不方便。 每次登录跳板机还要打开手机输入 Google authenticator 的安全码，有点蛋疼，效率也低。 SecureCRT 可以使用 python 实现自动登录 安装 Google authenticator 的 python 实现 pip install pyotp 自动登录脚本 # $language = "python" # $interface = "1.0" # This automatically generated script may need to be # edited in order to work correctly. import sys,pyotp sys.path.insert(0, "/usr/local/lib/python2.7/site-packages") // 这里是pip install pyotp之后，pip 的 packeages 目录，不然会报 import Error def Main(): crt.Screen.Synchronous

I am trying to use one-time passwords that can be generated using Google Authenticator application . What Google Authenticator does Basically, Google Authenticator implements two types of passwords: HOTP - HMAC-based One-Time Password, which means the password is changed with each call, in compliance to RFC4226 , and TOTP - Time-based One-Time Password, which changes for every 30-seconds period (as far as I know). Google Authenticator is also available as Open Source here: code.google.com/p/google-authenticator Current code I was looking for existing solutions to generate HOTP and TOTP
