Free Random Password Generator

Weak passwords get cracked; NToolHub’s Random Password Generator makes strong ones effortless. Built on your browser’s cryptographic random source, it creates passwords with the exact length and character mix you specify — uppercase, lowercase, digits, and symbols — and can generate batches of 50 at once for teams or testing. Nothing is stored or transmitted.

🔒
Private by design. This tool runs 100% in your browser — nothing is uploaded to any server.

How to Use the Random Password Generator

  1. Set the password length with the slider (4–64 characters).
  2. Choose which character sets to include, and optionally exclude ambiguous characters.
  3. Click “Generate Passwords” for secure results.
  4. Copy any password individually, or copy the whole batch.

Features

Passwords are generated with cryptographic randomness and rejection sampling for unbiased character selection. The tool guarantees at least one character from each selected set, offers an ambiguous-character filter (0, O, 1, l, I), and supports lengths from 4 to 64 characters with batch generation up to 50.

Benefits & Use Cases

Unique, random passwords are the single best defense against credential-stuffing attacks. Generating them locally means your passwords never touch a server, and the batch mode is perfect for provisioning accounts or rotating credentials across services.

Tips

Use 16 or more characters for important accounts, and include all four character sets. Store generated passwords in a reputable password manager rather than reusing them. The ambiguous-character filter helps when you must read a password aloud or type it from paper.

Frequently Asked Questions

Are these passwords safe to use for banking?

Yes. They are generated with cryptographic randomness in your browser and never leave your device. Pair them with a password manager and two-factor authentication.

Why do my passwords always include each character type?

The generator guarantees at least one character from every set you select, which satisfies most password policies. The remaining characters are fully random.

What are ambiguous characters?

Characters that look alike, such as zero and capital O, or one and lowercase L. Excluding them prevents typos when reading or typing passwords.

Do you store the passwords I generate?

No. Generation happens entirely in your browser. Nothing is sent to any server, logged, or stored.
