4.16 Password Invalidator Authentication

Introduction

The Password Invalidator is a feature in ZTrust that helps keep user accounts secure. It automatically forces users to change their login passwords after a predefined time period. This ensures that weak, old, or compromised passwords are regularly updated, keeping your organization's data safe.

Why Use Password Invalidator? (Use Cases)

1. Admin defines a password validity period (e.g., 30 days, 45 days, 60 days).

2. When the period ends, the Password Invalidator forces the user to reset their password on the next login.

3. Set up warning emails to notify users before their password expires, so they can be aware and update their password on time.

• Enhanced Security

  • The system makes you change your password regularly so that old or weak passwords don’t put your account at risk.

• Compliance with Company Policies

  • Some organizations require you to change your password after a certain time.

  • This feature automatically enforces those rules.

• Reduce Unauthorized Access Risks

  • If someone manages to steal your password, they can’t use it for long because it will expire after the set time.

• Warning Notifications

  • You’ll receive notifications before your password expires, so you have time to update it without being locked out.

Step 1 – Login to ZTrust Admin Console

• Open your ZTrust Admin Console in your browser.

• Sign in with your admin credentials.
