How long should a secure password be?▼
A secure password should be at least 16 characters long. Our generator defaults to 20 characters with uppercase, lowercase, numbers, and symbols for maximum security with over 130 bits of entropy.
Are the passwords truly random?▼
Yes. We use the Web Crypto API (crypto.getRandomValues) which provides cryptographically secure random numbers. This is the same technology used by password managers like 1Password and Bitwarden.
Is it safe to generate passwords online?▼
With SnapTools, yes. The password is generated entirely in your browser using JavaScript. It never touches our servers or any network connection. You can verify this by disconnecting from the internet and the tool will still work.
What makes a password strong?▼
Password strength depends on length and character variety. A strong password uses uppercase, lowercase, numbers, and symbols. Our strength meter shows the entropy in bits — aim for at least 80 bits for important accounts.
