📌 Frequently Asked Questions
Are the passwords generated here truly random?
Yes. This tool uses the `crypto.getRandomValues()` method, which is a cryptographically secure random number generator built into modern web browsers. This provides a much higher degree of randomness than standard math functions.
Are my generated passwords saved or seen by anyone?
No. The entire process of generating your password happens on your own computer. It is never transmitted over the internet, and we do not store or see the passwords you create.
What makes a password "strong"?
A strong password has three key characteristics: length (the longer, the better), complexity (a mix of uppercase letters, lowercase letters, numbers, and symbols), and randomness (it does not form a recognizable word or pattern). This tool helps you create passwords that meet all three criteria.
Free Password Generator: Create Strong, Random & Secure Passwords
Introduction: Your First Line of Defense in Cybersecurity
In today's digital landscape, a strong and unique password for every account is your most critical defense against unauthorized access and data breaches. Using simple, reusable, or predictable passwords is a major security risk. The Password Generator from NexaPrep Tools is a free, secure, and powerful online tool designed to create strong, random passwords that are extremely difficult for humans or computers to guess. With customizable options for length and character types, you can generate a password that meets any security requirement. The entire generation process happens in your browser, ensuring the passwords you create are never seen by us or transmitted over the internet.
What Makes a Password Strong?
A strong password is not just a random word. It has three essential characteristics, all of which our tool helps you achieve:
- Length: This is the single most important factor. A short password can be cracked by brute force in seconds, while a long one can take centuries. We recommend a minimum length of 16 characters for important accounts.
-
Complexity: A password that uses a mix of
different character types is exponentially harder to crack. Our
generator allows you to include:
- Uppercase Letters (A-Z)
- Lowercase Letters (a-z)
- Numbers (0-9)
- Symbols (!@#$%^&*)
- Randomness: A strong password should not contain dictionary words, common names, or predictable patterns (like "12345"). Our tool uses a cryptographically secure random number generator to ensure that the characters are truly random and unpredictable.
How to Generate Your Secure Password: A Simple Guide
Creating a new, strong password is an instant process:
- Set the Password Length: Use the slider or the number input to choose the desired length for your password.
- Select Character Types: Check the boxes to include or exclude uppercase letters, lowercase letters, numbers, and symbols. For maximum security, we recommend including all four types.
- Generate and Copy: Click the "Generate New Password" button. A new, random password will instantly appear in the display box. Simply click on the password itself to copy it to your clipboard.
After generating, be sure to save your new password in a secure location, preferably a trusted password manager application.
The Technology Behind Secure Randomness
Not all "random" generators are created equal. Many simple scripts use the standard `Math.random()` function, which is not designed for cryptographic security and can sometimes produce predictable patterns. Our tool, however, uses the `window.crypto.getRandomValues()` method. This is a special function built into modern web browsers that is specifically designed to generate cryptographically secure random numbers, making it suitable for security-sensitive applications like generating passwords, keys, and tokens. This ensures that the passwords you create have the highest degree of randomness possible from a browser-based tool.
Your Security is Our Priority
A password generator that transmits your new password over the internet would be a massive security flaw. That's why the NexaPrep Tools Password Generator is a 100% client-side tool. The entire process—from selecting your options to generating the random characters—happens on your own computer. The password you create is never sent to our servers, logged, or stored. It exists only on your screen and in your clipboard when you choose to copy it. This makes our tool a completely safe and private way to create the strong passwords you need to protect your digital life.

Why a Strong Password Matters
A weak password can be cracked in seconds. A strong, random 16-character password with mixed characters would take billions of years to brute-force. Our Password Generator creates cryptographically random passwords that no dictionary attack can crack.
How to Generate a Strong Password
- Set the length — 16+ characters recommended.
- Include uppercase, lowercase, numbers, and symbols for maximum strength.
- Click "Generate" — a new password is created instantly.
- Click "Copy" to copy it to your clipboard.
Password Security Tips
- 🔐 Never reuse passwords across different sites.
- 🔑 Use a password manager (Bitwarden, 1Password, KeePass) to store passwords safely.
- 📏 The longer the password, the exponentially stronger it is.
- �� Avoid personal information (birthdays, names) in passwords.
- 🔄 Change passwords immediately if a site you use announces a breach.
About Our Randomness
Passwords are generated using the browser's crypto.getRandomValues() API — a cryptographically
secure random number generator that ensures true unpredictability.
