Generate strong, cryptographically secure passwords. Customize length, uppercase, numbers, and symbols 100% locally using Web Crypto API.
About This Tool
Weak passwords like '123456', 'password', or reused login credentials are the leading cause of account takeovers and credential stuffing cyberattacks. Cybersecurity experts recommend using unique, long, random passwords combining uppercase letters, lowercase letters, numbers, and special symbols for every online service. Our browser-native Password Generator utilizes the Web Cryptography API (crypto.getRandomValues()) to produce high-entropy, unpredictable password strings. You can customize password length (8 to 128 characters), toggle character sets, exclude ambiguous characters (like O and 0, l and 1), and test password strength entropy scores. Because all password generation algorithms execute in local client-side memory, generated passwords are completely private. No password data is ever uploaded, logged, or transmitted over the internet.
Frequently Asked Questions
What makes a password strong?
A strong password is long (16+ characters), random, and combines uppercase, lowercase, numbers, and symbols.
Why is Web Crypto API better than standard Math.random()?
Math.random() is pseudo-random and predictable. crypto.getRandomValues() uses hardware entropy for cryptographic security.
Can I generate pronounceable passphrase passwords?
Yes, select 'Passphrase Mode' to generate memorable multi-word combinations.
Works on mobile phones and tablets?
Yes, fully responsive across mobile Safari, Chrome, Edge, and Firefox.
Can I generate passwords in bulk?
Yes, select 'Bulk Mode' to generate up to 100 secure passwords at once.
How long should my passwords be for high security?
Cybersecurity agencies recommend passwords be at least 16 characters long.
Can I use these passwords for password managers like 1Password or Bitwarden?
Yes! Generated passwords can be pasted directly into 1Password, Bitwarden, LastPass, or Dashlane.
Is any software installation required?
