PasswordReusePolicy

It is a module/gem to set the password resue policy for the registered users. Means you can set a limit, only after which a user will be able to resue the same password. For example if a user's password is "12345" and limit is 3, then he can only use password "12345" again after setting three different password.

It should work with any authentication library which supports either active record or mongoid ORM. In case you have any difficulty in using this module in your applicaition do write me at naveenagarwal287@gmail.com

Add this line to your application's Gemfile:

gem 'password_reuse_policy'

And then execute:

$ bundle

Or install it yourself as:

$ gem install password_reuse_policy

I am setting the example here for rails app, you can use it in any ruby app.

Configuration:

create a file named password_reuse_policy.rb

To add default configuration:

PasswordReusePolicy::Configuration.default!

To override default configuration:

PasswordReusePolicy::Configuration.config do |c|
  c.number_of_passwords_cannot_be_used = 3 #default, number of last used password which can not be used
  c.error_field_name = :password #default, error field name in which error will be set
  c.password_field_name = :password #default, field name from which password should be picked
endc

Link to sample applciation, devise is used for authentication, it uses password field name by default in the model.

To check the usage with active record visit https://github.com/naveenagarwal/password_reuse_policy_testapp Make sure you have there is a column exists in the table named last_used_passwords as text DataType when using with active_record.

To check the usage with mongoid visit https://github.com/naveenagarwal/password_reuse_policy_testapp/tree/mogoid_module_test
