Why Password Security Matters
Understanding the mechanics of digital security helps you make better decisions about your online identity.
The Danger of Reuse
When you reuse a password across multiple sites, a breach on a low-security forum can compromise your high-security banking or email accounts. Attackers use automated "credential stuffing" tools to test leaked passwords across thousands of popular websites simultaneously.
Speed of Attacks
Modern graphics cards can guess billions of passwords per second. An 8-character lowercase password is cracked instantly.
The Passphrase Advantage
Four random words (e.g. "correct horse battery staple") provide massive entropy while remaining easy for humans to remember.
