What Makes a Password Strong?
A strong password is long, random, and unique. Length is the most important factor because it exponentially increases the number of possible combinations. Randomness ensures there are no patterns for attackers to exploit. Uniqueness means each account gets its own password so a breach on one site does not compromise others.
Frequently Asked Questions
At least 12 characters for most accounts. For high-security accounts like email and banking, 16 or more characters is recommended.
No. The password is generated entirely in your browser using the Web Crypto API and is never sent to any server.
Both can be secure. Passphrases (random words strung together) are easier to remember. Passwords with mixed characters are shorter but harder to type. Use whichever you prefer, backed by a password manager.
