Question 1

Is this password generator safe to use?

Accepted Answer

Yes. All passwords are generated using the Web Crypto API (crypto.getRandomValues) directly in your browser. No data is ever sent to a server. You can verify by checking the source code or browser network inspector.

Question 2

How many bits of entropy should a strong password have?

Accepted Answer

For most purposes, 80+ bits of entropy is considered strong. A 20-character password with uppercase, lowercase, numbers, and symbols provides about 131 bits — far beyond brute force capability. For critical accounts, aim for 100+ bits.

Question 3

What does brute force time mean?

Accepted Answer

Brute force time estimates how long an attacker trying 1 trillion passwords per second would take to crack your password. Real-world attacks are usually slower due to rate limiting and slow hash algorithms like bcrypt.

Question 4

Can I generate passwords without symbols?

Accepted Answer

Yes. Toggle off the Symbols option to generate passwords with only letters and numbers. Some older systems don't accept special characters. The entropy display updates to show the impact on strength.

Question 5

Is a longer password always better?

Accepted Answer

Generally yes — each additional character exponentially increases the number of possible combinations. A 16-character password is billions of times harder to crack than an 8-character one. We recommend at least 16 characters for important accounts.

Question 6

Does this work offline?

Accepted Answer

Yes. Since all generation happens client-side using the Web Crypto API, you can save this page and use it offline. No internet connection or server is needed.
