The biggest password mistake isn't a weak password — it's the same password everywhere. When one site is breached, attackers try that email-and-password combo on every other service. A password manager removes the problem entirely.
Why reuse is so dangerous
Billions of leaked credentials are freely traded. 'Credential stuffing' tools try them automatically across banks, email, and social media. If your password is unique per site, a single breach stays contained.
What a password manager does
It generates a long, random password for every account and remembers them, so you only memorize one strong master password. Logging in becomes a tap, and every account gets a password no human could guess.
Choosing and starting one
Pick a reputable manager (built into your browser or phone is a fine start). Import saved passwords, then change the reused ones for important accounts first: email, banking, and your main social accounts.
Pair it with 2FA
A password manager plus two-factor authentication on key accounts is the practical gold standard for most people — strong, and low-effort once set up.
Frequently asked questions
Is it safe to keep all passwords in one place?
Reputable managers encrypt your vault so even they can't read it. The risk of reusing weak passwords across sites is far greater than the risk of a well-secured manager.
What if I forget the master password?
Set up the recovery options the manager offers and store a backup securely. The master password is the one thing you must not lose.
