Passcode
Passcode implements one-time passcode generators as standardized by the Initiative for Open Authentication (OATH). The HMAC-Based One-time Password (HOTP) algorithm defined by RFC 4226 and the Time-based One-time Password (TOTP) algorithm defined in RFC 6238 are supported.
Passcode is a heavily modified version of speakeasy incorporating the verification functions of notp.
Install
npm install --save passcode
Usage
var passcode = require("passcode");
var token = passcode.hotp({
secret: "xyzzy",
counter: 123
});
// token = "378764"
var ok = passcode.hotp.verify({
secret: "xyzzy",
token: token,
counter: 123
});
// ok = {delta: 0}
