node-argon2

Password Hashing Using NodeJS' Built-in Argon2 Implementation.

Installation

Support for crypto.argon2 was implemented in NodeJS 24.7.0, make sure you have the same or later version.

npm i node-argon2

Usage

import { hash, verify } from 'node-argon2';

const password = 'correct-horse-battery-staple';

const passwordHash = await hash(password);
console.log(await verify({ password, hash: passwordHash })); // true

The default algorithm is argon2id with parameters memory=9216, iterations=4, parallelism=1. You can change these by passing them as parameters to hash():

const passwordhash = await hash(
  password,
  {
    memory: 19_456,
    iterations: 2,
    parallelism: 1,
  },
  'argon2d',
);

The package is also fully compatible with better-auth:

import { betterAuth } from 'better-auth';
import * as password from 'node-argon2';

export const auth = betterAuth({
  // ...rest of the options
  emailAndPassword: {
    password,
  },
});
