## What it is
Passwordless is a Rails engine that adds magic-link (email-based) authentication to Rails applications without passwords. It provides a session model, controller helpers, and configurable token delivery and expiry.

## Use cases
- add magic link login to a Rails app
- authenticate users without passwords
- sign in users via emailed links
- replace Devise with a lightweight auth solution
- restrict controller access to signed-in users
- implement email-based session authentication

## When to choose
- you have a Rails app and want simple email magic-link authentication
- you want to avoid storing and managing passwords
- you want a minimal, mountable auth engine you can customize

## When to avoid
- you need multi-factor authentication or OAuth/social login
- you're not using Ruby on Rails
- you need a full-featured auth suite with registrations and password resets out of the box
