Password Generator

Generate strong, random passwords with customizable length and character types. Password security is one of the most important aspects of online safety, and using unique, complex passwords for every account is the single best practice to prevent unauthorized access. This tool uses the cryptographically secure Web Crypto API to generate truly random passwords entirely in your browser. Adjust the length, include uppercase, lowercase, numbers, and symbols to meet any password policy requirement.

Length: 20

Uppercase (A-Z)

Lowercase (a-z)

Numbers (0-9)

Symbols (!@#$...)

Password Security Best Practices

A strong password is your first line of defense against hackers, data breaches, and identity theft. Reusing passwords across multiple sites is extremely risky — if one site is compromised, all your accounts become vulnerable. This generator creates cryptographically random passwords that are far stronger than anything humans typically choose. For maximum security, use a password manager to store unique 20+ character passwords for every account you own.

Frequently Asked Questions

How long should a password be?Use at least 16 characters for important accounts. 20+ characters with mixed character types provides very strong protection against brute-force attacks.

What does "bits of entropy" mean?Entropy measures password randomness in bits. 80+ bits is strong, 100+ bits is very strong. A 20-character password with all character types has approximately 131 bits of entropy.

Should I use a password manager?Yes. Password managers generate, store, and autofill unique strong passwords for every site. They eliminate the need to remember or reuse passwords, which is the biggest security risk.
