Kingsman: Configuring Models
The Kingsman method in your models also accepts some options to configure its modules. For example, you can choose the cost of the hashing algorithm with:
app/models/user.rb
class User < ApplicationRecord
kingsman :database_authenticatable, :registerable, :confirmable, :recoverable, stretches: 13
end
Besides :stretches, you can define :pepper, :encryptor, :confirm_within, :remember_for, :timeout_in, :unlock_in among other options. For more details, see the initializer file that was created when you invoked the kingsman:install generator described above. This file is usually located at config/initializers/kingsman.rb.
