How long should a password be?
NIST recommends at least 16 characters for high-value accounts. A 16-character random password with mixed characters has 95¹⁶ ≈ 4.4 × 10³¹ possible combinations — effectively impossible to brute force.
Random Password Generator creates cryptographically secure passwords instantly using your browser's built-in secure random number generator. Choose your desired length, which character sets to include (uppercase, lowercase, numbers, symbols), and generate as many passwords as you need. Your passwords are never sent to any server and are generated entirely on your device.
Passwords are generated using crypto.getRandomValues(), the browser's built-in CSPRNG (Cryptographically Secure Pseudo-Random Number Generator). Characters are drawn randomly from the selected pool (uppercase: A-Z, lowercase: a-z, numbers: 0-9, symbols: !@#$%^&*). No patterns, no seeds, no predictability.

Yes. The tool uses crypto.getRandomValues() which is a CSPRNG suitable for security applications. Passwords are as random as your browser's secure random generator allows.
No. Password generation runs entirely in your browser. Your passwords never leave your device. No logs, no storage, no server.
Yes, if the target site allows them. Including symbols significantly increases entropy. For sites that ban symbols, a longer all-alphanumeric password compensates.
Absolutely not. If one site is breached, all your accounts become vulnerable (credential stuffing). Use a unique password for every account and store them in a password manager.
Yes, completely free. No account, no limits on how many passwords you generate.
