How SafePass.pro Works

Local Generation, Zero Storage

When you open SafePass.pro, the entire generator runs in your web browser using JavaScript. Passwords are built with crypto.getRandomValues(), the same cryptographically secure API used by password managers and security tools. Your generated password is never transmitted to our servers and is never logged.

Step-by-Step: Using the Generator

1. Choose your settings. Set password length (8–128 characters) and toggle character sets: uppercase, lowercase, numbers, and symbols. Advanced options let you exclude similar characters (like l and 1), duplicates, or sequential patterns.
2. Generate instantly. A new random password appears immediately. Click regenerate anytime for a fresh credential.
3. Check the strength meter. SafePass.pro scores your password based on length, character diversity, and common patterns. Aim for "Strong" or "Very Strong" before using it.
4. Run a breach check. The tool queries the Have I Been Pwned database to see if your password has appeared in known data breaches.
5. Copy or export. Copy the password to your clipboard or export an AES-encrypted text file protected by a passphrase you choose.

How Breach Checking Protects Your Privacy

SafePass.pro uses the k-anonymity model from Have I Been Pwned. Instead of sending your full password to the API, only the first five characters of its SHA-1 hash are transmitted. The API returns all matching hash suffixes, and your browser compares them locally. Your complete password never leaves your device during a breach check.

Memorable and Easy-to-Read Modes

Need a passphrase you can type from memory? Use our passphrase generator to create multi-word passwords from the EFF large wordlist. For router credentials, the Wi-Fi password generator produces strong WPA2/WPA3 passwords and includes a QR code share so guests scan the password onto their phone instead of typing it.

Dedicated Password Tools

SafePass.pro includes focused generators for common use cases — each runs entirely in your browser:

• Passphrase generator — diceware-style multi-word passphrases
• Wi-Fi password generator — random router passwords for WPA2/WPA3, with QR share to phone
• PIN generator — secure 4, 6, or 8-digit PINs
• Password strength checker — test an existing password and check Have I Been Pwned

What SafePass.pro Does Not Do

• Store passwords in a database
• Require an account or email address
• Track which passwords you generate
• Send passwords to third parties (except the partial hash for breach checks)
