Password Generator – Create Strong Secure Passwords
Generate random, secure passwords with custom options for length, symbols, numbers, and letter case. This free password generator helps you create passwords for accounts, apps, and devices quickly and safely.
Why Use a Password Generator?
Strong unique passwords protect accounts from automated attacks and credential reuse. A password generator creates unpredictable combinations that are difficult to guess or brute force. Using a different password for each account reduces risk in case a single site is compromised.
What Makes a Password Strong?
Password strength depends on length and complexity. Longer passwords and a larger variety of characters increase entropy and make a password harder to crack. Combining lowercase, uppercase, numbers, and symbols is a standard best practice.
How to Use This Generator
- Choose password length (recommended minimum 12 characters).
- Toggle character sets: lowercase, uppercase, numbers, symbols.
- Optionally exclude ambiguous characters like I, l, 1, O, 0.
- Click Generate and copy the result to your clipboard.
- Store the password securely in a password manager.
Best Practices
- Use a password manager to store unique passwords for each account.
- Avoid reusing passwords across sites and services.
- Enable two factor authentication when available.
- Choose passwords with length and variety rather than simple substitutions.
Security Notes
This tool generates passwords in the browser. No generated password is sent to any server. For maximum safety, copy the password directly to a password manager and do not paste it into insecure places. If you need programmatic password generation for applications, use platform libraries that derive keys with appropriate cryptographic standards.
Understanding Entropy and Strength
Entropy is a measure of unpredictability. This generator estimates strength using a simple entropy calculation based on chosen character sets and length. Higher entropy implies more resistant to attacks. For human memorability, consider using a password manager rather than trying to memorize very long random strings.
Who Should Use This Tool?
Individuals, teams, developers, and IT administrators can use this generator to create secure passwords for accounts, test logins, demo environments, and protected documents. It is also useful for creating tokens and API keys during development.

Final Notes
Strong passwords and good account hygiene greatly reduce the chance of unauthorized access. Use this generator to build strong credentials and combine it with a password manager and multi factor authentication for best protection.
