The cybersecurity community has been recommending password managers for over a decade. Yet a majority of internet users still reuse the same password — or a minor variation of it — across multiple sites. The consequences show up in breach statistics every year.

Why Reuse Is So Dangerous

When a website suffers a data breach and its password database is leaked, attackers run “credential stuffing” attacks: they automatically try those username and password combinations against hundreds of other services. If you reuse a password from a breached site on your bank or email account, attackers get in — no hacking required.

What a Password Manager Actually Does

• Generates truly random, long, unique passwords for every account.
• Stores them encrypted — the manager itself cannot read your passwords.
• Auto-fills on the correct site only, protecting against phishing replicas.
• Works across all your devices with one master password.

Choosing One

Well-regarded options include Bitwarden (open source, free tier), 1Password, and Dashlane. Avoid storing passwords in browser built-ins if you share devices, as these are often not encrypted at rest.

The One Password You Do Need to Remember

Your master password for the manager should be a passphrase: four or more random words strung together. Something like “correct-horse-battery-staple” is both memorable and extremely hard to crack. Enable MFA on the manager account itself for an extra layer of protection.
