Complete Guide to Password Managers

A password manager securely stores all your passwords so you only need to remember one strong master password. This guide explains how they work, their security model, and how to choose the right one.

How Password Managers Work

Password managers encrypt your password vault using your master password as the encryption key. The encryption happens on your device — reputable managers use zero-knowledge architecture, meaning they cannot see your passwords even if they wanted to.
