Strong Password Generator
Generate strong random passwords with adjustable length and character types. Free to use, no signup required for occasional use.
What is the Password Generator?
The Password Generator is a free online tool that creates strong, random passwords using a cryptographically secure random source, with full control over length and which character types are included. Reusing weak or predictable passwords is one of the most common ways accounts get compromised, and manually coming up with a genuinely random password that also satisfies a site's character requirements is harder than it sounds — human-generated 'random' passwords tend to be far less random than they feel. This tool lets you set an exact password length and toggle uppercase letters, lowercase letters, numbers, and symbols on or off independently, so you can match whatever a specific service requires. As you generate a password, a strength indicator gives you an at-a-glance sense of how strong the result is based on its length and character variety, helping you catch a configuration that's too weak (like a short, letters-only password) before using it. This is useful for developers setting up test accounts, anyone creating a new account online, or IT staff generating temporary credentials that meet an organization's password policy.
How to use it
Use the length slider to set how many characters your password should be — longer passwords are generally stronger. Toggle the checkboxes for Uppercase, Lowercase, Numbers, and Symbols depending on what character types you want included, or what a particular website's password policy requires. Click 'Generate password' and a new random password appears immediately, built from a cryptographically secure random source using only your selected character types. Check the strength indicator below the result to confirm it meets the security level you need; if it looks weak, try increasing the length or enabling more character types and generate again. Once you're happy with it, use the copy button to copy the password directly to your clipboard, then paste it into the account signup form or password manager you're setting it for. Avoid reusing the same generated password across multiple accounts — generate a fresh one each time.
Frequently asked questions
How random are the generated passwords?
Passwords are generated using a cryptographically secure random source, not a simple pseudo-random function, which makes them suitable for real account security.
Can I control which character types are used?
Yes, you can independently toggle uppercase letters, lowercase letters, numbers, and symbols to match a specific password policy.
What does the strength indicator measure?
It estimates strength based on password length and the variety of character types used, giving a quick weak-to-very-strong signal for the generated result.
Should I reuse a generated password across multiple sites?
No, it's best practice to generate and use a unique password for each account, ideally stored in a password manager.
