bcrypt_user_auth

🔑 Use has_secure_password for User Model

Rails provides a quick way to handle password hashing with the bcrypt gem. By adding has_secure_password to your User model, Rails will automatically add virtual password and password_confirmation attributes and handle validation and authentication methods for you.

1. Add bcrypt to your Gemfile and run bundle install.

# Gemfile
gem 'bcrypt', '~> 3.1.7'

2. Generate a migration to add the password_digest column to users.

rails generate migration AddPasswordDigestToUsers password_digest:string
rails db:migrate

3. Update your User model.

class User < ApplicationRecord
  has_secure_password
end
