Strong Passwords FAQ
Why use a password generator?
Password generators create random, secure passwords that are much harder for attackers to guess or brute force than human-created ones.
How long should a strong password be?
Experts recommend at least 12 characters. Longer is always stronger, especially when combined with symbols and numbers.
Can I reuse the same password?
Never reuse passwords across sites. If one site is breached, all your accounts could be at risk. Use a password manager instead.
Is this generator secure?
Yes. Everything runs client-side in your browser. No data is sent to servers, so your generated passwords remain private.
Should I write down my generated passwords?
It’s best not to write them on paper. Instead, use a trusted password manager to store them securely. If you must write one down, keep it in a safe, private place.
What characters make the strongest passwords?
Passwords that mix uppercase, lowercase, numbers, and special symbols are strongest. Avoid dictionary words and predictable patterns like “1234” or “password”.
How often should I change my passwords?
Change passwords immediately if a service you use has been breached. For critical accounts like email or banking, rotating passwords every 6–12 months adds an extra layer of safety.
Is a longer password always better than a complex one?
Yes, length matters most. A 16+ character passphrase (even with simple words) can be stronger than an 8-character password full of symbols. Ideally, use both length and complexity.
