How long should my password be?
At least 12 characters. 16+ is ideal for sensitive accounts.
Should I always include symbols?
They increase strength, but some sites restrict certain characters. Match the site's requirements.
What Makes a Password Actually Strong?
A strong password combines uppercase, lowercase, numbers, and symbols -- and it's at least 12 characters long. The longer and more varied it is, the more combinations an attacker has to try. A 16-character random password has more possible combinations than there are atoms on Earth.
Password Strength: The Math Behind It
Password strength is measured in bits of entropy. A password using all 95 printable ASCII characters at 12 characters long has about 79 bits of entropy -- that's 2^79 possible combinations. At a billion guesses per second, it would take longer than the age of the universe to crack. Aim for 80+ bits.
Why You Need a Different Password for Every Site
When a website gets hacked, stolen passwords often end up in "credential stuffing" attacks -- where hackers automatically try those same username/password combinations on hundreds of other sites. If you reuse passwords, one breach can compromise dozens of accounts. A password manager like Bitwarden or 1Password lets you use unique, strong passwords everywhere without memorizing them.
Strong Passwords Are Just the Start: Add 2FA
Even the strongest password can be stolen through phishing or data breaches. Two-factor authentication (2FA) means an attacker needs your password AND access to your phone or authenticator app. App-based 2FA (Google Authenticator, Authy) is more secure than SMS codes, which can be intercepted through SIM swapping. Enable 2FA on every account that supports it.
Password Patterns Hackers Try First
"123456", "password", and "qwerty" top the annual lists of most-used passwords. Beyond the obvious, attackers try name+birthdate combinations, keyboard walks (asdfgh, qwerty), and substitutions (p@ssw0rd). Dictionary attacks and rule-based crackers handle all of these instantly. The only safe password is one that looks completely random -- which is exactly what this generator produces.
