Why You Need a Strong Password
Weak passwords are the #1 cause of data breaches. A 6-character lowercase password can be cracked in under a second, while a 16-character mixed password with symbols would take billions of years with current hardware. Our password generator makes creating unbreakable passwords effortless.
Every password generated by this tool uses the Web Crypto API — the same cryptographic engine that secures HTTPS connections. Combined with entropy analysis, you can be confident that your passwords meet or exceed industry security standards.
"Use a strong, unique password" is advice everyone gives but nobody follows when they have to make one up themselves. This generator creates cryptographically random passwords using the Web Crypto API — not the predictable Math.random(). Customize length, character types, and exclusions. The password never leaves your browser — it's generated locally and exists only in your tab.
Key Features
Cryptographically Secure
Uses the Web Crypto API (crypto.getRandomValues) for true randomness — the same standard used by banking and security applications. No pseudo-random shortcuts.
100% Offline & Private
Passwords are generated entirely in your browser. Nothing is transmitted over the network, stored on a server, or logged anywhere. Your credentials stay on your device.
Entropy-Based Strength Analysis
See real-time entropy (in bits) and a strength label for every generated password. Understand exactly how resistant your password is to brute-force attacks.
Password & Passphrase Modes
Generate traditional character-based passwords or human-readable passphrases (e.g., "Correct-Horse-Battery-Staple"). Passphrases are easier to remember and still highly secure.
Granular Customization
Control length, character types (uppercase, lowercase, numbers, symbols), exclude similar characters (l, I, 1, O, 0), require one from each category, and more.
Batch Generation & Export
Generate up to 50 passwords at once. Copy them individually, copy the entire list, or regenerate any single entry — perfect for provisioning multiple accounts.
Who Is This Tool For?
Everyday Users
Create strong, unique passwords for email, social media, banking, and online shopping accounts. Stop reusing the same password across sites.
System Administrators
Provision secure credentials for databases, APIs, SSH keys, and service accounts. Batch-generate passwords for multiple team members at once.
Mobile Users
Works perfectly on phones and tablets. Generate a secure password on the go and paste it directly into your password manager or registration form.
Security-Conscious Teams
Enforce minimum entropy requirements for your organization. The strength meter makes it easy to verify passwords meet your security policy.
Password vs. Passphrase: Which Should You Use?
| Criteria | Password | Passphrase |
|---|---|---|
| Example | k#9Xm!pQ2v | Correct-Horse-Battery |
| Memorability | Difficult | Easy |
| Typing Speed | Slow (mixed chars) | Fast (words) |
| Entropy (typical) | 60–80 bits | 65–90 bits |
| Best For | Password managers | Manual entry |
How to Use the Password Generator
- Choose a mode: Select "Password" for random characters or "Passphrase" for a sequence of dictionary words.
- Set the length: Use the slider to pick your desired length (8–128 characters for passwords, 4–12 words for passphrases).
- Customize characters: Toggle uppercase, lowercase, numbers, symbols. Enable "Exclude similar" to avoid l/I/1/O/0 confusion.
- Check strength: Review the entropy meter. Aim for at least 80 bits for important accounts.
- Copy or generate more: Use Ctrl+C to copy, Ctrl+G to regenerate. Generate a list of 10+ passwords for batch provisioning.
