A password manager encrypts and stores your login credentials behind a single master password, auto-filling them when you visit a saved site. It solves the memorization problem — but it doesn't automatically make weak passwords strong.

What a password manager actually protects you from

• Reusing the same password across multiple accounts
• Choosing memorable-but-guessable passwords out of convenience
• Losing track of dozens or hundreds of unique logins

What it doesn't replace

The vault is only as secure as the individual passwords stored inside it and the master password protecting the vault itself. A manager filled with genuinely weak, short passwords still leaves those individual accounts exposed if a breach exposes the raw credentials elsewhere.

Pairing the two properly

Generate a long, random, unique password for every new account with a password generator, save it directly into your manager, and never reuse it. The manager handles memory; the generator handles strength.
