You’ve probably been told to use a password manager — but how does handing all your passwords to one app actually keep them safe? It sounds risky until you understand what’s happening under the hood.
This guide explains, in plain English, how password managers work: the encrypted vault, the master password, the encryption, and how your passwords sync across devices without ever being exposed.
What a Password Manager Does
A password manager securely stores all your login credentials in an encrypted vault. Instead of remembering dozens of passwords (or reusing one risky password everywhere), you remember a single master password that unlocks the vault. The app then fills in your logins automatically and can generate strong, unique passwords for every account.
