🔑 Random Password Generator

Click "Generate Password" to start.

Password Length: 16

Character Sets:

Uppercase (A-Z)

Lowercase (a-z)

Numbers (0-9)

Symbols (!@#$...)

A minimum length of 16 characters and all four character types is highly recommended for security.

🚀 How the Password Generator Works

**User Configuration:** You select your preferences: the desired **length** (we recommend 16+) and the **character sets** to include (Uppercase, Lowercase, Numbers, and Symbols).
**Character Pool Creation:** The tool compiles all the selected character sets into one massive pool of available characters. For example, if all four boxes are checked, the pool contains $\text{26 (upper)} + \text{26 (lower)} + \text{10 (numbers)} + \text{~30 (symbols)} \approx \text{92 characters}$.
**Cryptographic Randomness:** The generator uses the browser's built-in **`window.crypto.getRandomValues()`** API. This is a secure, **cryptographically strong** source of randomness, making the generated passwords truly unpredictable, unlike those created using simple `Math.random()`.
**Secure Selection:** The tool loops for the specified length, and for each position, it securely selects a character from the pool using the cryptographic random values. This ensures a high degree of **entropy** (randomness).
**Client-Side Execution:** **The entire process happens in your browser.** The tool does not use a server to generate or store the password, guaranteeing complete privacy and security.

❓ Frequently Asked Questions

1. Is it truly random and secure?

Yes. The tool uses the **browser's Cryptographic Random Number Generator (CRNG)**, which is the most secure method available in JavaScript for generating keys and passwords. The resulting passwords are highly unpredictable and resistant to brute-force attacks.

2. Is my generated password recorded or stored?

Absolutely not. The password generation process is **100% client-side**. The password is created, displayed, and copied all within your web browser's memory. It is never transmitted to our server, nor is it stored anywhere after you close the tab.

3. What is the minimum recommended password length?

Security standards have evolved. We recommend a minimum length of **16 characters** for critical accounts. While 8-12 characters might be common, they are increasingly vulnerable to cracking, especially when combined with common word lists. Longer is always better.

4. Why is using symbols and numbers important?

Including different character types increases the **character pool size** (entropy). For a 16-character password, using all four types ($\approx 92$ total characters) creates exponentially more combinations than just using letters ($\approx 52$ characters), drastically increasing the time required to crack the password.

5. Should I use a password manager for these passwords?

Yes! **Always use a reputable password manager** (like 1Password, Bitwarden, or LastPass) to store the strong, unique passwords generated by this tool. Relying on your memory or insecure notes defeats the purpose of creating highly secure credentials.
