Password Generator

Generate strong, random passwords with custom length and character sets including uppercase, lowercase, numbers and symbols.

Why you need strong passwords

Weak passwords are one of the most common causes of account breaches. A password like "password123" can be cracked in under a second using modern brute-force tools. A strong, randomly generated password of 16 characters using mixed character types would take thousands of years to crack with current computing power.

What makes a password strong

• Length: Minimum 12 characters; 16+ is recommended for important accounts.
• Complexity: Mix of uppercase (A–Z), lowercase (a–z), numbers (0–9), and symbols (!@#$).
• Randomness: Avoid words, names, dates, or keyboard patterns like "qwerty".
• Uniqueness: Never reuse passwords across different accounts.

Password strength guide

Weak: Under 8 characters or only one character type. Medium: 8–11 characters with two types. Strong: 12+ characters with three types. Very Strong: 16+ characters with all four types.

How to manage strong passwords

Since strong passwords are hard to remember, use a trusted password manager like Bitwarden, 1Password, or Dashlane to store them securely. Enable two-factor authentication (2FA) on every important account as an extra layer of security even if your password is compromised.

Is this tool safe

Yes. This password generator runs entirely in your browser using the Web Crypto API for cryptographically secure random number generation. No passwords are sent to any server, logged, or stored anywhere.

Frequently asked questions

How long should a strong password be?

A minimum of 12 characters is recommended for most accounts. For high-value accounts like email, banking, and cloud storage, use 16 or more characters. Longer passwords are exponentially harder to crack even with simple character sets.

Is it safe to use this password generator?

Yes. This tool uses the Web Crypto API (crypto.getRandomValues) which generates cryptographically secure random numbers. The password is generated entirely in your browser and is never sent to any server or stored anywhere.

What does the strength rating mean?

Very Strong means 16+ characters with all four character types (uppercase, lowercase, numbers, symbols). Strong means 12+ characters with three types. Medium means 8–11 characters with two types. Weak means under 8 characters or only one type.

Should I use the same password on multiple websites?

No. If one site is breached, attackers will try that password on other services (credential stuffing). Use a unique password for every important account and store them in a password manager like Bitwarden or 1Password.

What are the strongest characters to include?

All four types together create the strongest passwords. Symbols like !@#$%^&* add the most complexity because they expand the character set the attacker must try for each position in a brute-force attack.
