The average person has hundreds of accounts and cannot possibly remember a strong, unique password for each. So they reuse them. When one site is breached, attackers try that password everywhere else — and often get in. A password manager solves this at the root.
What a password manager does
- Generates long, random, unique passwords for every account.
- Stores them in an encrypted vault unlocked by one strong master password.
- Auto-fills credentials, so you rarely type them — which also reduces what a keylogger can capture.
- Warns you about reused, weak, or breached passwords.
You only have to remember one strong password. The manager remembers the rest — perfectly.
Choosing one
Look for a manager with a strong security track record, zero-knowledge encryption (the provider cannot read your vault), cross-device sync, and two-factor protection on the account itself. Both reputable cloud services and offline options work; pick what you will actually use.
Master password tips
- Make it a long passphrase — four or more random words beat a short complex string.
- Never reuse it anywhere else.
- Protect the vault with 2FA, ideally a hardware key or authenticator app.
💡
Bonus against keyloggersBecause the manager auto-fills instead of you typing, a basic keystroke logger captures far less. Pair it with 2FA (explained here) for strong, layered protection.
