An enterprise security extension for devise, trying to meet industrial standard security demands for web applications.


  • captcha support for sign_up, sign_in, recover and unlock (to make automated mass creation and brute forcing of accounts harder)

Model modules

  • :password_expirable - passwords will expire after a configured time (and will need an update)

  • :secure_validatable - better way to validate a model (email, stronger password validation). Don't use with :validatable!

  • :password_archivable - save used passwords in an old_passwords table for history checks (don't be able to use a formerly used password)

  • :session_limitable - ensures, that there is only one session usable per account at once

  • :expirable - expires a user account after x days of inactivity (default 90 days)


Add to Gemfile

gem 'devise_security_extension'

after bundle install

rails g devise_security_extension:install

for :secure_validatable you need to add

gem 'rails_email_validator'


Devise.setup do |config|
  # Should the password expire (e.g 3.months)
  # config.expire_password_after = 3.months

  # Need 1 char of A-Z, a-z and 0-9
  # config.password_regex = /(?=.*\d)(?=.*[a-z])(?=.*[A-Z])/

  # How often save old passwords in archive
  # config.password_archiving_count = 5

  # Deny old password (true, false, count)
  # config.deny_old_passwords = true

  # captcha integration for recover form 
  # config.captcha_for_recover = true

  # captcha integration for sign up form
  # config.captcha_for_sign_up = true

  # captcha integration for sign in form
  # config.captcha_for_sign_in = true

  # captcha integration for unlock form
  # config.captcha_for_unlock = true

  # ==> Configuration for :expirable
  # Time period for account expiry from last_activity_at
  config.expire_after = 90.days



  1. add to Gemfile “gem 'easy_captcha'”

  2. install easy_captcha “rails g easy_captcha:install”

  3. enable captcha - see “Configuration”

  4. add captcha source in the devise views for each controller you have activated

<p><%= captcha_tag %></p>
<p><%= text_field_tag :captcha %></p>

That's it!


Password expirable

create_table :the_resources do |t|

Password archivable

create_table :old_passwords do |t|
add_index :old_passwords, [:password_archivable_type, :password_archivable_id], :name => :index_password_archivable

Session limitable

create_table :the_resources do |t|


Devise 2.0 style migrations on new resource:

create_table :the_resources do |t|
  t.datetime :last_activity_at
  t.datetime :expired_at

Add module to existing resource with

change_table :the_resources do |t|
  t.datetime :last_activity_at
  t.datetime :expired_at

  • Check out the latest master to make sure the feature hasn't been implemented or the bug hasn't been fixed yet

  • Check out the issue tracker to make sure someone already hasn't requested it and/or contributed it

  • Fork the project

  • Start a feature/bugfix branch

  • Commit and push until you are happy with your contribution

  • Make sure to add tests for it. This is important so I don't break it in a future version unintentionally.

  • Please try not to mess with the Rakefile, version, or history. If you want to have your own version, or is otherwise necessary, that is fine, but please isolate to its own commit so I can cherry-pick around it.
