How to Create a Strong Password
A strong password is your first line of defense against hackers and data breaches. Our free password generator uses the Web Crypto API — the same technology trusted by banks — to generate truly random, unpredictable passwords directly in your browser.
The four pillars of password strength:
Length — Every extra character makes your password exponentially harder to crack. Aim for 16+ characters for important accounts.
Randomness — Human-chosen passwords follow predictable patterns. A generator eliminates this completely.
Character variety — Mixing uppercase, lowercase, numbers, and symbols dramatically increases the number of possible combinations.
Uniqueness — Never reuse passwords. One breach shouldn't compromise everything you own online.

Why Use a Passphrase?
Passphrases combine random words into strings like Coral-Ridge-Falcon-74. They're easier to type and remember than random character strings, while being extremely difficult to crack. A 4-word passphrase has billions of possible combinations — perfect for accounts you type manually, like your laptop login.
Where Should I Store My Passwords?
Use a reputable password manager. You only need to remember one strong master password — the manager handles the rest with military-grade encryption. Top options include Bitwarden (free and open source), 1Password, and NordPass.
