# Time based One Time Password
Simple TOTP, one function to call and generate OTP token.
This is a no-depenencies package
# Install
if you are using Yarn:
```sh
yarn add @frani/totp
```
if you are using NPM:
```sh
npm i @frani/totp
```
# Usage
to generate:
```js
const totp = require("@frani/totp");
const token = totp.generate({
secret: "123", // optional - default is 'secret'
timeStep: 30, // optional - default is 30 seconds
digits: 6, // optional - default is 6
});
console.log(token); // 480143
```
in case you want to compare, simple regenerate and check with '===', example:
```js
const totp = require("@frani/totp");
const CODE = "123123";
const token = totp.generate({
secret: "123", // optional - default is 'secret'
timeStep: 30, // optional - default is 30 seconds
digits: 6, // optional - default is 6
});
console.log(token); // 480143
if (CODE === token) return true; // is false
```
