How to Generate a Strong Random Password
This free password generator tool creates secure, random passwords using your browser’s built-in cryptographic random number generator — the same technology trusted by security-focused applications.

Why You Need a Strong, Random Password
Weak or reused passwords are one of the most common causes of account takeovers and data breaches. A strong password generator helps you create a unique random password for every account, protecting you against brute-force attacks, credential stuffing, and dictionary-based hacking attempts.
Avoid Predictable Patterns
Human-created passwords often follow predictable patterns. A random password generator removes that weakness entirely.
Use a Unique Password for Every Site
Reusing passwords means one data breach can expose all your accounts. Generate a new one for each login.
Longer is Stronger
Every extra character exponentially increases the time needed to crack a password by brute force.
Mix Character Types
Combining uppercase, lowercase, numbers, and symbols greatly increases password strength and entropy.
Password Strength Levels Explained
This tool measures password strength based on entropy — the total number of possible combinations based on length and character variety.
Frequently Asked Questions About This Password Generator
Is this password generator really secure?
Yes. It uses your browser’s built-in cryptographically secure random number generator (Web Crypto API) rather than a weaker pseudo-random method, producing truly unpredictable passwords.
Are my generated passwords saved or sent anywhere?
No. Everything happens locally in your browser. Passwords are never transmitted to any server or stored anywhere — not even in this browser tab once you leave the page.
What is the ideal password length?
Most security experts recommend at least 12–16 characters mixed with uppercase, lowercase, numbers, and symbols for strong protection.
Can I generate multiple passwords at once?
Yes, use the “Generate Multiple” option to create up to 100 random passwords in one click, then copy or download them all.
What does “Exclude Similar Characters” do?
It removes easily confused characters like i, l, 1, L, o, 0, and O — useful if you need to type or read the password manually.
Is this password generator free to use?
Yes, completely free with no sign-up, no limits, and no watermark.
Password Security Tips
Beyond using a strong password generator, follow these best practices to keep your accounts secure: use a different random password for every account, enable two-factor authentication (2FA) wherever available, store your passwords in a trusted password manager instead of writing them down, avoid using personal information like birthdays or names, and change passwords immediately if a service you use reports a data breach. Combining a secure random password generator with these habits significantly reduces the risk of account compromise.
