What is a password generator?
A password generator creates long, random passwords that are extremely hard for attackers to guess or crack. Humans are predictable — we reuse pet names, birthdays and simple patterns — and that predictability is exactly what password-cracking software exploits. This generator uses your browser's cryptographically secure random number source, so every password is genuinely unpredictable and unique.
What makes a password strong?
Two things matter most: length and variety. A longer password has exponentially more possible combinations, and mixing uppercase, lowercase, numbers and symbols widens the pool further. The strength meter above shows entropy in bits — a rough measure of how many guesses an attacker would need. Anything above 70 bits is strong for most accounts; above 100 bits is excellent. As a rule, aim for at least 16 characters wherever a site allows it.
Staying safe with passwords
A strong password only helps if you use a different one for every account, because a leak on one site should never unlock the others. The realistic way to manage dozens of unique passwords is a reputable password manager, which stores and fills them for you. Wherever possible, also switch on two-factor authentication, which adds a second barrier even if a password is ever exposed. For more on account safety, see the official guidance from CISA.
Frequently Asked Questions
Are these passwords really random?
Yes. The generator uses the browser's built-in cryptographic random source, which is designed to be unpredictable and suitable for security use.
Is my password sent over the internet?
No. Passwords are created locally in your browser and never transmitted or stored. Close the tab and they are gone.
How long should my password be?
Aim for at least 16 characters where the site allows it. Longer passwords are dramatically harder to crack.
Should I reuse a strong password everywhere?
No. Use a unique password for every account and store them in a trusted password manager so a single leak cannot compromise your other logins.
