History
Why Strength Matters
In an era of automated hacking tools and massive data breaches, a basic password like Summer2024! is no longer sufficient. A Strong Password Generator creates complex, unpredictable credentials that are mathematically resilient against brute-force attacks.
Powerful Features
Batch Generation
Need to create accounts for an entire team? Toggle Batch Mode to generate up to 100 unique passwords in a single click.
No Ambiguity
Avoid confusion between 1, l, and I. Our "Exclude Ambiguous" option ensures every character is clearly readable.
Maximum Security
Powered by the browser's window.crypto, ensuring true cryptographic randomness that cannot be predicted.
Full Control
Fine-tune length (6-64 chars) and character sets (A-Z, a-z, 0-9, symbols) to meet any site's specific requirements.

Frequently Asked Questions
Is this password generator truly secure?
Yes. We use the Web Crypto API (window.crypto), which provides cryptographically strong random values. All generation happens locally in your browser; passwords are never sent to our servers.
What makes a password "strong"?
A strong password generally has high entropy, meaning it is long (16+ characters) and uses a mix of uppercase, lowercase, numbers, and symbols. It avoids predictable patterns and dictionary words.
Can I generate multiple passwords at once?
Yes! Toggle the "Batch Mode" switch to generate up to 100 passwords simultaneously. This is useful for admins or setting up multiple accounts.
What are "ambiguous characters"?
Ambiguous characters look similar and can be confusing, such as the letter "I" (uppercase i), "l" (lowercase L), and the number "1". Our tool allows you to exclude these to make passwords easier to read.
Do you store or save the generated passwords?
Absolutely not. This tool is client-side only. Once you refresh the page or close the tab, the generated passwords vanish forever.
Why should I use a random password generator?
Humans are naturally bad at randomness. We tend to use patterns (like "password123") that hackers can easily guess. A random generator removes this bias, creating creating mathematically complex strings.
What is the recommended password length?
For most secure uses, 16 characters is the modern standard. 12 characters is the minimum we recommend, and anything above 20 provides extreme protection.
Is it safe to copy passwords to the clipboard?
Yes, but be mindful. Clipboard history can sometimes be accessed by other apps. We recommend pasting it immediately into your password manager and clearing your clipboard if you are on a shared device.
Can I use this for Wi-Fi passwords?
Yes. Randomly generated passwords are excellent for WPA2/WPA3 Wi-Fi security. We recommend excluding symbols if your router has trouble with them, but keeping the length high (20+ chars).
Does this work offline?
Yes. Once the page is loaded, the Javascript code runs entirely in your browser. You can even disconnect your internet and it will still work perfectly.
