About this tool

What is a random password generator?

A random password generator is a free online security tool that creates strong passwords with adjustable length from 8 to 64 characters and toggleable character sets including uppercase, lowercase, numbers, and symbols. Every password is generated using browser-native cryptographic randomness, and no password is ever sent to a server or stored anywhere -- users can verify this in their browser developer tools. The tool supports generating multiple unique passwords at once and copying any result to clipboard with one click for immediate use. It is commonly used for creating secure account passwords that resist brute-force and dictionary attacks, generating Wi-Fi and device passwords for home and office networks, producing API keys and database credentials for development and staging environments, building strong credentials for password manager vaults, and replacing weak or reused passwords across online services and applications. A 16-character mixed password would take billions of years to crack with current computing power. Entirely client-side with no signup required.

When you'd use this.

Account Security

Every online account needs a unique, strong password. Our generator creates passwords that are virtually impossible to crack by brute force. A 16-character password with mixed characters would take billions of years to crack with current computing power.

Wi-Fi & Device Passwords

Setting up a new router or device? Generate a strong password you can share with family or guests. Use the "exclude ambiguous characters" option to avoid confusion between similar-looking characters like O/0 and l/1.

Developer & IT Use

Developers generate passwords for API keys, database credentials, test accounts, and service tokens. The batch generation feature lets you create multiple unique passwords at once for configuring multiple services.

Frequently asked.

Is this password generator safe to use?+
Yes. All passwords are generated entirely in your browser using JavaScript. No password is ever sent to our servers or stored anywhere. You can verify this by checking the network tab in your browser's developer tools.
What makes a strong password?+
A strong password is at least 12 characters long and includes a mix of uppercase letters, lowercase letters, numbers, and special symbols. Our generator defaults to these settings. Longer is always better — 16+ characters is recommended.
Can I generate multiple passwords at once?+
Yes, use the quantity selector to generate up to 10 unique passwords in one click. Each password is independently generated and guaranteed to be unique.
Why not just use my browser's password manager?+
You absolutely should use a password manager! Our tool is useful when you need a password outside of a browser context (Wi-Fi setup, app registration, sharing with someone) or when you want more control over the format.
How long should my password be?+
For most accounts, 16 characters is the sweet spot between security and usability. For high-security applications (banking, email), use 20+ characters. Our default is 16 characters.
