## What it is
Authlogic is an unobtrusive Ruby authentication library built on ActiveRecord, treating user sessions as models. It handles login, logout, remember-me, and session persistence for Rails applications without generators or controllers scaffolding.

## Use cases
- add user login and logout to a rails app
- authenticate users with a password against activerecord models
- manage user sessions with remember-me and timeout support
- replace devise with a simpler authentication solution
- implement csrf-protected session auth in rails

## When to choose
- you want model-based, unobtrusive authentication in a Ruby on Rails app
- you need fine-grained control over session behavior without generator-generated code
- you prefer a lightweight alternative to Devise

## When to avoid
- you need a batteries-included solution with views, mailers, and OAuth out of the box
- you are building an API-only app needing token/JWT authentication
- you are not using ActiveRecord or Rails

## Facets
- artifact type: library
- maturity: stable
- function: auth, middleware
- domain: web-development, backend, security
- platform: ruby
- tags: activerecord, rails, session-management, user-authentication, login, web-server
