otp - TOTP library for Go

  •    Go

One Time Passwords (OTPs) are an mechanism to improve security over passwords alone. When a Time-based OTP (TOTP) is stored on a user's phone, and combined with something the user knows (Password), you have an easy on-ramp to Multi-factor authentication without adding a dependency on a SMS provider. This Password and TOTP combination is used by many popular websites including Google, Github, Facebook, Salesforce and many others. The otp library enables you to easily add TOTPs to your own application, increasing your user's security against mass-password breaches and malware.

Google Authenticator - Two factor authentication

  •    Java

The Google Authenticator project includes implementations of one-time passcode generators for several mobile platforms, as well as a pluggable authentication module (PAM). One-time passcodes are generated using open standards developed by the Initiative for Open Authentication (OATH). These implementations support the HMAC-Based One-time Password (HOTP) algorithm specified in RFC 4226 and the Time-based One-time Password (TOTP) algorithm specified in RFC 6238.
