Frequently Asked Questions

No. All password generation occurs client-side in your browser using JavaScript. The passwords are never transmitted over the internet or saved to any database.

We utilize the Web Crypto API (`crypto.getRandomValues()`), which provides cryptographically strong random values. This is significantly more secure than standard `Math.random()`.

Entropy is a mathematical measure of how unpredictable a password is, calculated based on its length and the size of the character pool used.

We recommend a minimum of 16 characters for online accounts. For high-security services, aim for 20-24 characters or more.

Yes! Since SecureGen relies completely on client-side technologies without external backend dependencies, you can load the page, disconnect your internet, generate your password, and close the tab.

A passphrase is a sequence of words (e.g., 'correct-horse-battery-staple') that is often easier for humans to remember but long enough to be secure against cracking.

If you reuse a password and one site is compromised, hackers will try that same email and password combination on thousands of other sites (credential stuffing).

A brute-force attack is when a hacker uses automated software to guess every possible combination of characters until they find the correct password.

A 16-character password using uppercase, lowercase, numbers, and symbols would take modern supercomputers trillions of years to crack via brute force.

While better than reusing passwords, dedicated password managers (like Bitwarden, 1Password, or Dashlane) are generally considered more secure and feature-rich than browser-based managers.

2FA adds a second layer of security to your accounts by requiring an additional credential, such as a time-based code from an authenticator app, in addition to your password.

No, we do not use tracking cookies or third-party analytics cookies. We respect your privacy.

The PIN generator creates a random sequence of numbers of your desired length, useful for phone locks, physical vaults, or 2FA recovery codes.

Characters like 'l' (lowercase L) and '1' (number one) look identical in many fonts, leading to confusion when you need to type the password manually.

Yes, our advanced generator allows you to create up to 100 passwords simultaneously, which you can then export as a TXT or CSV file.

It's a theoretical estimate of how long it would take an array of high-end GPUs to guess your password by trying every combination. It highlights the importance of length.

Yes, SecureGen is fully responsive and optimized to work seamlessly on smartphones and tablets.

You should change a password immediately if you suspect the account was compromised. Routine password rotation is no longer recommended by NIST unless there is a known breach, provided the password is strong and unique.

Passkeys are a modern alternative to passwords that use cryptography and biometrics (like FaceID or TouchID) to authenticate you without needing to type or remember a secret string.

Yes, SecureGen is 100% free to use, and we plan to keep it that way.
