What is Random Password Generator?
Random Password Generator builds cryptographically strong passwords using the browser's crypto.getRandomValues. Pick length, character classes (lowercase, uppercase, digits, symbols), and exclude ambiguous characters (O/0, l/1) — the generated password is unique to your session and never leaves the page. Strong, memorable, and ready to paste into your password manager.
Why use this tool?
- Your data stays private — all processing happens locally in the browser
- No telemetry, no tracking pixels, no third-party scripts
- Open-and-go: bookmark the page once and never look for an alternative
- No telemetry on the tokens, payloads, or code you paste in
- Built for developer workflows: copy-friendly output, syntax-aware highlighting where useful
How to use
- Paste the input you want to process
- Adjust any optional flags or formatting settings
- Run the conversion — everything happens locally in your browser
- Copy the output for use in your project
Examples
Generate a 16-character mixed password
With length 16 and all character classes enabled, you get something like Ks7#fQ2!nLp$8vXz — high entropy, hard to crack.
Build a pronounceable passphrase
Switch to passphrase mode and get 4-6 random dictionary words separated by hyphens — easier to type, still strong (~50 bits per 4 words).
Skip ambiguous characters
Toggle "exclude similar" and the generator avoids 0/O, 1/l/I, |/I — useful for passwords you may have to dictate or read off a screen.
Common use cases
- Creating unique passwords for every account in a password manager
- Generating service account / API credentials in CI scripts
- Producing one-time recovery codes for users
- Building default admin passwords for self-hosted installations
- Generating short PINs or tokens for verification flows
Troubleshooting
- Site rejected my password as too long.
- Some legacy sites cap at 16-20 characters. Reduce length and ensure all required character classes are included.
- Symbols disallowed by the target system.
- Disable the symbols class and increase length to keep entropy high. A 24-char alphanumeric is stronger than a 12-char mixed-symbol password.
- How do I remember this?
- You don't — use a password manager (1Password, Bitwarden, KeePass). Memorise one strong master password and let the manager handle the rest.
Frequently Asked Questions
A secure password should be at least 12 characters long, include a mix of uppercase and lowercase letters, numbers, and special symbols. Avoid common words, patterns, or personal information.
