🔐 Strong Password Generator
Generate secure, uncrackable passwords instantly. Customize length and character types. 100% client-side — your passwords never leave your device.
🛡️ Password Security Best Practices
Creating strong passwords is your first line of defense against hackers. Follow these essential tips:
Length Over Complexity
A 16-character password is exponentially stronger than an 8-character one. Aim for 16+ characters.
Mix Character Types
Use uppercase, lowercase, numbers, and symbols. Each type multiplies cracking difficulty.
Avoid Personal Info
Never use birthdays, names, or common words. These are the first things hackers try.
Unique Per Account
Generate a different password for every account. One breach won't compromise everything.
⚡ How Password Strength Works
The Math Behind Cracking
Password strength is measured in entropy (bits). The more possible combinations, the longer it takes to crack:
- 8-character password (lowercase only): 26^8 = 208 billion combinations → cracked in seconds
- 12-character mixed password: 95^12 = 540 sextillion combinations → cracked in millennia
- 16-character mixed password: Would take longer than the age of the universe to crack
Why This Generator is Secure
Our generator uses crypto.getRandomValues(), a cryptographically secure random number
generator (CSPRNG) built into modern browsers. This is the same entropy source used by banking
applications and security software. The password is generated entirely in your browser — nothing is
ever sent to a server.
❓ Frequently Asked Questions
For maximum security, use at least 16 characters. While 8 characters was once acceptable, modern computers can crack short passwords quickly. A 16-character password with mixed characters is essentially uncrackable with current technology.
Yes! This generator uses crypto.getRandomValues(), a cryptographically secure random number generator built into your browser. It's the same standard used by banking apps. Plus, your passwords are generated locally — they never touch our servers or the internet.
Absolutely. Including special characters (!@#$%^&*) significantly increases password strength. They expand the character set from 62 (letters+numbers) to 95+ characters, making brute-force attacks exponentially harder.
Don't try to memorize them! Use a password manager like Bitwarden (free), 1Password, or LastPass. They securely store all your passwords behind one master password. This lets you use unique, complex passwords for every account.
Only change passwords if you suspect a breach or if a service notifies you of one. Current security research shows that forcing regular password changes often leads to weaker passwords. Instead, use unique, strong passwords and enable two-factor authentication.
