password_policy

This is a Drupal 8 module for the Password Policy module. This is comprised of constraints and policies.

Constraints are different ways that you can restrict a password. A policy is an instance of a constraint that define specific parameters for the constraint.

Policies are applied through Drupal's role-based permissions system.

Password Policy comes bundled with a password expiration feature. Policies define a time-based expiration logic (based on days) and administrators have the ability to manually expire all passwords by role.

Enable

• Download and enable the module

Plugins

All plugins are installed as separate modules. The only policies that are out of the box is the Password Reset feature.

• Password Expiration (time-based or manually forced, built in feature of Password Policy)
• Password Length (submodule of Password Policy)
• Zxcvbn (https://github.com/nerdstein/password_policy_zxcvbn)

Configure

• Enable all plugin modules
• Go to Password Policy's configuration page (/admin/config/security/password/settings)
• Add policies by clicking on the tab for each plugin
• Go to the permissions page (/admin/people/permissions)
• Select which roles the policies applies to

Architecture

• Password policy provides a plugin manager that defines an interface for constraints and the constraint's policies
• Policies are implemented as permissions and enforced on the user form
• Password expiration implements an event subscriber and forces a user to his/her user form upon expiration
• Password time-based expiration leverages cron for tagging accounts as expired
