How to Generate a Secure Password
Choose password length and character types: uppercase, lowercase, numbers, and symbols.
Click Generate to create a cryptographically random password.
Click Copy and store it in a password manager — never in plain text files.
Why Use a Password Generator?
A password generator creates truly random passwords using cryptographic randomness, making them far more secure than human-created passwords. Humans tend to use dictionary words, predictable patterns, and reuse passwords across accounts. A randomly generated 16-character password has approximately 10^30 possible combinations, making it practically impossible to crack. Using unique random passwords stored in a password manager is the single most effective step for online security.
Best Practices for Password Security
Use a unique randomly generated password for every account. Set length to at least 16 characters. Include all character types to maximize search space. Store all passwords in a reputable password manager like Bitwarden, 1Password, or KeePass. Enable two-factor authentication wherever available. Never share passwords via email — use your password manager's secure sharing feature.
Frequently Asked Questions
How long should my password be?
At least 16 characters for important accounts. For critical accounts (banking, email), consider 20+ characters.
Are special characters necessary?
They significantly increase security. However, a longer password with fewer character types can be equally secure — length matters more than complexity.
How does this generator create random passwords?
We use the Web Crypto API (crypto.getRandomValues), which provides cryptographically secure random numbers from your operating system.
Should I use a passphrase instead?
Passphrases need to be at least 4-5 random words (20+ characters) to match a 16-character random password. For most people, a password manager with random passwords is more practical.
