  # :mongoid (bson_ext recommended) by default. Other ORMs may be
  # available as additional gems.
  require "devise/orm/#{DEVISE_ORM}"

  # ==> Configuration for any authentication mechanism
  # Configure which keys are used when authenticating a user. By default is
  # just :email. You can configure it to use [:username, :subdomain], so for
  # authenticating a user, both parameters are required. Remember that those
  # parameters are used only when authenticating and not when retrieving from
  # session. If you need permissions, you should implement that in a before filter.
  # You can also supply hash where the value is a boolean expliciting if authentication
  # should be aborted or not if the value is not present. By default is empty.
  # config.authentication_keys = [:email]

  # Configure parameters from the request object used for authentication. Each entry
  # given should be a request method and it will automatically be passed to
  # find_for_authentication method and considered in your model lookup. For instance,
  # if you set :request_keys to [:subdomain], :subdomain will be used on authentication.
  # The same considerations mentioned for authentication_keys also apply to request_keys.
  # config.request_keys = []

  # Configure which authentication keys should be case-insensitive.
  # These keys will be downcased upon creating or modifying a user and when used
  # to authenticate or find a user. Default is :email.
  config.case_insensitive_keys = [:email]

  # Configure which authentication keys should have whitespace stripped.
  # These keys will have whitespace before and after removed upon creating or
  # modifying a user and when used to authenticate or find a user. Default is :email.
  config.strip_whitespace_keys = [:email]

  # Tell if authentication through request.params is enabled. True by default.

  # using other encryptors, it sets how many times you want the password re-encrypted.
  config.stretches = Rails.env.test? ? 1 : 10

  # ==> Configuration for :confirmable
  # The time you want to give your user to confirm their account. During this time
  # they will be able to access your application without confirming. Default is nil.
  # When allow_unconfirmed_access_for is zero, the user won't be able to sign in without confirming.
  # You can use this to let your user access some features of your application
  # without confirming the account, but blocking it after a certain period
  # (ie 2 days).
  # config.allow_unconfirmed_access_for = 2.days

  # Defines which key will be used when confirming an account
  # config.confirmation_keys = [:email]

  # ==> Configuration for :rememberable
  # The time the user will be remembered without asking for credentials again.
  # config.remember_for = 2.weeks

  # If true, extends the user's remember period when remembered via cookie.
  # config.extend_remember_period = false

  # ==> Configuration for :validatable
  # Range for password length. Default is 8..72.
  # config.password_length = 8..72

  # Regex to use to validate the email address
  # config.email_regexp = /^([\w\.%\+\-]+)@([\w\-]+\.)+([\w]{2,})$/i

  # ==> Configuration for :timeoutable
  # The time you want to timeout the user session without activity. After this
  # time the user will be asked for credentials again. Default is 30 minutes.
  # config.timeout_in = 30.minutes

  # ==> Configuration for :lockable
  # Defines which strategy will be used to lock an account.
  # :failed_attempts = Locks an account after a number of failed attempts to sign in.
  # :none            = No lock strategy. You should handle locking by yourself.
  # config.lock_strategy = :failed_attempts

  # Defines which key will be used when locking and unlocking an account
  # config.unlock_keys = [:email]

  # Defines which strategy will be used to unlock an account.
  # :email = Sends an unlock link to the user email
  # :time  = Re-enables login after a certain amount of time (see :unlock_in below)
  # :both  = Enables both strategies
  # :none  = No unlock strategy. You should handle unlocking by yourself.
  # config.unlock_strategy = :both

  # Number of authentication tries before locking an account if lock_strategy
  # is failed attempts.
  # config.maximum_attempts = 20

  # Time interval to unlock the account if :time is enabled as unlock_strategy.

  # ==> Configuration for :recoverable
  #
  # Defines which key will be used when recovering the password for an account
  # config.reset_password_keys = [:email]

  # Time interval you can reset your password with a reset password key.
  # Don't put a too small interval or your users won't have the time to
  # change their passwords.
  config.reset_password_within = 2.hours

  # When set to false, does not sign a user in automatically after their password is
  # reset. Defaults to true, so a user is signed in automatically after a reset.
  # config.sign_in_after_reset_password = true

  # Set up a pepper to generate the encrypted password.
  config.pepper = "d142367154e5beacca404b1a6a4f8bc52c6fdcfa3ccc3cf8eb49f3458a688ee6ac3b9fae488432a3bfca863b8a90008368a9f3a3dfbe5a962e64b6ab8f3a3a1a"

  # ==> Scopes configuration
  # Turn scoped views on. Before rendering "sessions/new", it will first check for
  # "users/sessions/new". It's turned off by default because it's slower if you
  # are using only default views.
  # config.scoped_views = false

  # Configure the default scope given to Warden. By default it's the first
  # devise role declared in your routes (usually :user).
  # config.default_scope = :user

  # Configure sign_out behavior.
  # Sign_out action can be scoped (i.e. /users/sign_out affects only :user scope).
  # The default is true, which means any logout action will sign out all active scopes.
  # config.sign_out_all_scopes = true

  # ==> Navigation configuration
  # Lists the formats that should be treated as navigational. Formats like
  # :html, should redirect to the sign in page when the user does not have
  # access, but formats like :xml or :json, should return 401.
  # If you have any extra navigational formats, like :iphone or :mobile, you
  # should add them to the navigational formats lists. Default is [:html]
  # config.navigational_formats = [:html, :iphone]

  # The default HTTP method used to sign out a resource. Default is :get.

  # ==> OmniAuth
  config.omniauth :facebook, 'APP_ID', 'APP_SECRET', scope: 'email,offline_access'
  config.omniauth :openid
  config.omniauth :openid, name: 'google', identifier: 'https://www.google.com/accounts/o8/id'

  # ==> Warden configuration
  # If you want to use other strategies, that are not supported by Devise, or
  # change the failure app, you can configure them inside the config.warden block.
  #
  # config.warden do |manager|
  #   manager.failure_app = AnotherApp
  #   manager.default_strategies(scope: :user).unshift :some_external_strategy
