Generate Passwords
That Actually Protect You

Absolutely. All password generation happens locally in your browser using the crypto.getRandomValues() API. No data is ever transmitted to any server. You can verify this by checking your network tab.

We recommend at least 16 characters for strong security. For critical accounts (banking, email), 24–32 characters provides excellent protection. The longer the password, the more computationally expensive it is to crack.

Entropy measures the randomness of a password in bits. It's calculated as log₂(pool_size ^ length). Higher entropy means harder to crack. 128 bits is considered very strong — equivalent to a 128-bit encryption key.

Yes, using uppercase, lowercase, numbers, and symbols together maximizes the character pool, significantly increasing entropy and crack time. The only reason to disable a type is if a specific service doesn't accept it.

It removes characters that look similar in many fonts — like 0/O, 1/l/I, |/. This is useful if you need to manually type a password and want to avoid confusion.

Absolutely. The tool is fully responsive and works on all devices from 320px phones to ultrawide monitors. All features — generation, strength analysis, and copying — work identically on mobile.
