The **Password Health Checker** is a feature that gives you an overview of the security level of all passwords stored in Locker. ## Types of passwords detected * **Weak passwords:** Passwords that are too short, simple, or easy to guess. * **Reused passwords:** The same password used across multiple accounts. * **Exposed passwords:** Passwords that have appeared in publicly reported data breaches. ## How to use it Access the **Password Health** feature from the main menu in Locker on the Web Vault or mobile app. Locker will automatically analyze and display a list of passwords that need improvement. Regularly check your password health and promptly change any passwords that are weak, reused, or exposed to protect your accounts.
