Password Generator

Create Strong, Random Passwords

This password generator builds strong, random passwords you control down to the character. Set the length and choose which character sets to include: uppercase, lowercase, numbers, and symbols. A built-in strength meter gives you instant feedback so you can balance memorability against security, whether you need a quick throwaway credential or a long, high-entropy secret for a production account.

How it works

Passwords are generated entirely in your browser with JavaScript, drawing on the platform's cryptographic randomness. Because generation is local, no password is ever sent to, or stored on, a server, which is essential for a value meant to stay secret. Adjust the options and a fresh password appears immediately, ready to copy into your password manager or signup form. You can regenerate as many times as you want until you get a value you like, and nothing is remembered between passwords, so each one is independent and unpredictable.

Practical use cases

• Create a unique password for a new account or service
• Generate high-entropy secrets and API keys for development
• Produce database or admin credentials that meet complexity rules
• Quickly rotate a password that may have been exposed
• Generate a passphrase-length secret that satisfies strict length rules

For related needs, generate unique identifiers with the UUID Generator, hash a password with the Bcrypt Generator, or create checksums using the Hash Generator.

Every password is created in-browser and never leaves your device, so nothing you generate is logged, transmitted, or reused. The tool is free, requires no sign-up, and works in all modern browsers, including mobile, so you can create secure credentials wherever you are. Since it runs offline once the page has loaded, you can even generate passwords with the connection disabled for extra peace of mind.
