Why You Need Strong Passwords

In today's digital world, your passwords are the first line of defense against hackers and identity theft. Weak passwords can be cracked in seconds using modern computing power, putting your personal information, financial accounts, and online identity at risk.

Our free password generator creates truly random, cryptographically secure passwords that would take billions of years to crack with current technology. Each password is generated using the Web Crypto API, the same technology used by banks and security professionals.

Frequently Asked Questions

We recommend a minimum of 12-16 characters for most accounts. For highly sensitive accounts like banking, email, or cryptocurrency, use 20+ characters. Each additional character exponentially increases the time needed to crack your password. A 16-character password with all character types would take billions of years to crack.

Yes, absolutely. This password generator is completely safe because all passwords are generated locally in your browser. We use the Web Crypto API (crypto.getRandomValues), which provides cryptographically secure random numbers. No passwords are ever sent to our servers, stored in databases, or logged anywhere. You can even use this tool offline.

A strong password has three key properties: Length (at least 12 characters, ideally 16+), Complexity (mix of uppercase, lowercase, numbers, and symbols), and Uniqueness (different for every account). Random passwords are stronger than human-created ones because they have no patterns, personal information, or dictionary words that attackers can exploit.

Absolutely, yes. A password manager is essential for modern security. It lets you use unique, strong passwords for every account without memorizing them. Popular options include Bitwarden (free and open source), 1Password, and LastPass. Generate your passwords here, then store them securely in your password manager.

Password strength is measured in bits of entropy using the formula: Entropy = password length × log₂(character set size). For example, a 16-character password using all character types (94 possible characters) has about 105 bits of entropy. Passwords with 80+ bits are considered very strong and would take longer than the age of the universe to crack with brute force attacks.

Yes, significantly better. Humans are predictable—we use patterns, substitute letters with similar numbers (@ for a, 3 for e), and base passwords on personal information like birthdays or pet names. Hackers know these patterns and exploit them. Randomly generated passwords have no patterns, no personal connections, and maximum entropy, making them vastly more secure.
