Password Generator

Generate strong, unbiased random passwords with customizable length and character sets.

Generated Password

Password Preferences

Password Length: 18 characters

Uppercase Letters (A-Z)e.g. A, B, C, D...

Lowercase Letters (a-z)e.g. a, b, c, d...

Numbers (0-9)e.g. 1, 2, 3, 4...

Symbols & Special Characterse.g. !@#$%^&*

Exclude Ambiguous CharactersAvoids easily confused glyphs like 1, l, I, 0, O, Q, 8, B

Passwords are generated 100% locally in your browser using the cryptographically secure crypto.getRandomValues API with rejection-sampled unbiased selection. No passwords ever leave your machine.

About Password Generator

Free cryptographically secure password generator using browser crypto.getRandomValues with zero modulo bias. Configure length, symbols, numbers, and ambiguous characters with instant entropy evaluation.

Accepted Input:Custom character rules and length from 6 to 128

Output Result:Unbiased cryptographic password string with entropy rating

Processing model:Generated 100% inside your browser using hardware-backed cryptographic APIs. No passwords are ever sent across the network or stored.

How It Works

1Step 1

Select your desired length (e.g., 16 or 24 characters) using the quick presets or slider.

2Step 2

Check or uncheck uppercase, lowercase, numbers, special symbols, or exclude ambiguous characters.

3Step 3

Click 'Copy' to copy your new password to clipboard, or switch to 'Bulk Generation' to generate lists of passwords.

Common Use Cases

Creating highly secure, unique master passwords for password managers (1Password, Bitwarden, Apple Keychain).

Generating random API secrets, tokens, encryption salts, and database credentials.

Ensuring accounts meet strict corporate or service complexity requirements without predictable patterns.

Frequently Asked Questions

Quick answers to common questions for users and search assistants

Is this password generator truly random?

Yes. It utilizes the browser's native crypto.getRandomValues CSPRNG combined with rejection sampling to eliminate modulo bias. Every character is picked with uniform probability.

Does UtilityKit store or transmit the generated passwords?

No. All generation happens strictly in your browser's local memory. No passwords are ever transmitted or saved to any database or server log.

What is entropy and how is strength measured?

Entropy measures the theoretical unpredictability of the password in bits (Length × log2(character pool)). Passwords with 80+ bits of entropy are virtually unbreakable by offline brute force.
