## What it is
A Node.js/Express module that enables passwordless user authentication using one-time password (OTPW) tokens delivered via email or SMS. It provides middleware for Express apps to authenticate and authorize users without passwords.

## Use cases
- add passwordless login to an express app
- authenticate users via one-time email tokens
- let users sign in without passwords
- implement magic link authentication in node.js
- replace password-based auth with token-based login
- send one-time passwords by email or SMS

## When to choose
- you're building an Express app and want simple passwordless login
- you want faster onboarding without password management
- you prefer token-based one-time password authentication over passwords

## When to avoid
- you need a full-featured auth system with social login, MFA, or sessions management
- you're not using Node.js/Express
- you need actively maintained software with recent releases
- you require OAuth or SSO integrations
