Password Best Practices
Follow these tips to keep your accounts safe
🔒
Use 16+ characters
Longer passwords are exponentially harder to crack. Aim for at least 16 characters for important accounts.
🚫
Never reuse passwords
If one site is breached, reused passwords expose all your accounts. Use a unique password for every service.
🗝️
Use a password manager
Tools like Bitwarden, 1Password, or KeePass securely store and autofill your unique passwords — no memorization needed.
📱
Enable two-factor authentication
2FA adds a second layer of security. Even if your password is stolen, attackers can't access your account without the second factor.
🙅
Avoid personal information
Don't use your name, birthday, pet's name, or anything that can be found on your social media profiles.
⚡
Change compromised passwords immediately
Check sites like haveibeenpwned.com regularly. If your password appears in a breach, change it right away.
Frequently Asked Questions
Yes. This tool uses the browser's built-in Web Crypto API (crypto.getRandomValues) to generate cryptographically secure random passwords. All generation happens entirely in your browser — no data is sent to any server, and we never see, store, or transmit your passwords.
A strong password is long (16+ characters), uses a mix of uppercase letters, lowercase letters, numbers, and special characters, and is unique — never reused across multiple accounts. Avoid dictionary words, personal information, and simple substitutions like replacing 'a' with '@'.
Password entropy measures how unpredictable a password is, expressed in bits. It is calculated as: length × log₂(character set size). Higher entropy means the password is harder to crack. Security experts generally recommend at least 60–80 bits of entropy for most accounts. This generator shows the estimated entropy for every password it creates.
Passphrases can be both memorable and secure. A four-word diceware passphrase provides about 51 bits of entropy, while a random 16-character password from this generator typically achieves 80–110 bits. For accounts you must memorize, a passphrase is a great choice. For everything else, use a password manager with random passwords from this generator.
Current NIST guidelines recommend changing passwords only when there is a specific reason — such as a known breach, account compromise, or after sharing a password with someone. Focus on using unique, strong passwords for every account with a password manager, and enable two-factor authentication wherever possible.
