Frequently Asked Questions
A strong password is long (at least 12 characters), contains a mix of uppercase and lowercase letters, includes numbers and special characters, and does not use common words, patterns, or personal information. Strong passwords are unique for each account and are not found in known password breach lists.
A minimum of 12 characters is recommended. Longer passwords (16+ characters) provide significantly better security. Every additional character exponentially increases the number of possible combinations, making brute-force attacks impractical.
Crack time estimates how long it would take a computer to guess your password through a brute-force attack. It depends on password length, character variety, and the attacker's computing power. A strong password should take centuries to crack.
Avoid passwords like 'password', '123456', 'qwerty', 'admin', 'letmein', 'welcome', 'monkey', 'dragon', 'iloveyou', 'master', 'sunshine', 'princess', 'football', and any password found in known breach databases. Also avoid using the same password across multiple accounts.
