Module: Devise::Models::PasswordExpirable

Extended by:
ActiveSupport::Concern
Defined in:
lib/devise-security/models/password_expirable.rb

Overview

PasswordExpirable makes passwords expire after a configurable amount of time, or on demand.

Configuration

Set expire_password_after to the number of seconds a password is valid for (example: 3.months). Setting it to true will allow passwords to be expired on-demand only, and false disables this feature.

Expire On-Demand

This is useful to force users to change passwords for complex business reasons. Call need_change_password to indicate a record needs a new password.
