Frequently asked questions
How long should a password be?
A password of 16 characters or longer is considered strong for most accounts. Longer passwords provide exponentially better security.
What is password entropy?
Entropy measures password randomness in bits. Higher entropy means harder to crack. A password with 60+ bits of entropy is generally secure.
Why exclude ambiguous characters?
Characters like 0/O, 1/I, and l look identical in some fonts, causing confusion when typing or copying passwords. Excluding them prevents mistakes.
Is this password generator secure?
Yes. Passwords are generated locally in your browser and never sent to any server, so they remain private and secure.
Should I use symbols in my passwords?
Yes. Adding symbols increases password entropy and makes passwords harder to crack. Most online accounts require or recommend them for security.
