otp - One Time Password utilities Go / Golang

  •        228

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.

This library provides support in generating QR Code images for easy user enrollment. It supports both Time-based One-time Password Algorithm (TOTP) (RFC 6238) and HMAC-based One-time Password Algorithm (HOTP).
