Frequently Asked Questions
How strong should my password be?
For maximum security, use passwords that are at least 12-16 characters long and include a mix of uppercase letters, lowercase letters, numbers, and symbols. Our entropy meter shows password strength - aim for >60 bits for strong security. A 16-character password with all character types has about 100 bits of entropy.
Are these passwords secure?
Yes! Passwords are generated locally in your browser using the Web Crypto API's cryptographically secure random number generator. They are never sent to any server or stored anywhere. Each password is truly random and unpredictable. The entropy meter shows the password's information entropy - higher is better.
What is password entropy?
Password entropy measures how difficult a password is to guess. It's calculated based on length and character variety. Each bit of entropy doubles the number of guesses needed. A password with 60 bits of entropy would take centuries to crack with current technology. Our entropy meter and crack time estimate help you understand password strength.
Should I use the same password for multiple accounts?
No! Never reuse passwords across different accounts. If one account is compromised, all your accounts with the same password become vulnerable. Use a unique password for each account and consider using a password manager like LastPass, 1Password, or Bitwarden to securely store them.
