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.
