Secure Password Generator
Creating a strong, unpredictable password is your first line of defense against cyber threats. This free tool creates cryptographically secure passwords locally in your browser using the native crypto.getRandomValues() API. Whether you're quickly spinning up credentials for a new account or locking down highly sensitive data, your generated passwords never leave your device.
Frequently Asked Questions
How many characters should I use for a secure password?
Length is the most critical factor for security. While older systems may only accept 8 characters, modern standards recommend much more. Using 12 to 14 characters provides a good baseline for everyday accounts. For critical data, we highly recommend setting the slider to 15 characters or longer to make brute-forcing mathematically impossible.
Is this better than using a built-in password generator?
Browser and password manager generators are fine if you're already invested in those ecosystems. This tool is standalone — no account, no extension, no tracking. It works in any browser and gives you direct control over the character sets and length, which built-in generators often don't expose.
What makes the generated passwords safe?
It uses the browser's native Web Crypto API (crypto.getRandomValues()) rather than a basic mathematical randomizer. This provides cryptographic-quality entropy, making the output statistically unpredictable — even with knowledge of previous results.
Can I generate passwords using dictionary words?
Some users prefer passphrases to create memorable combinations. However, our tool focuses exclusively on creating highly complex, randomized character strings which provide the highest density of security per character, ideal for use alongside a trusted password manager.
What does "avoid ambiguous characters" mean?
Some characters look visually similar and can cause confusion when reading a password aloud or copying it manually — for example: 0 (zero) vs O (letter O), 1 (one) vs l (lowercase L) vs I (uppercase i). Enabling this setting removes these characters from the pool, preventing frustrating typos.
