Creating Strong Passwords
A strong password is your first line of defense against unauthorized access. This generator uses cryptographically secure randomness (Web Crypto API) to create passwords that are impossible to predict.
For maximum security, use passwords of at least 16 characters with a mix of uppercase, lowercase, numbers, and symbols. Alternatively, passphrases of 4+ random words provide excellent security while being easier to remember.
Frequently Asked Questions
How long should my password be?
At minimum 12 characters, but 16+ is recommended. Each additional character exponentially increases security. A 20-character random password would take millions of years to crack with current technology.
Is a passphrase better than a password?
Passphrases (like "correct-horse-battery-staple") can be more secure AND easier to remember than short complex passwords. A 4-word passphrase from a large dictionary provides excellent entropy while being memorable.
Are generated passwords really random?
Yes. This tool uses the Web Crypto API's getRandomValues() function, which provides cryptographically secure pseudo-random numbers. This is the same level of randomness used for encryption keys.
Should I use the same password everywhere?
Never. If one service is breached, all your accounts would be compromised. Use a unique password for each account and store them in a password manager. This generator makes creating unique passwords easy.
