Strong Password Generator
Create strong, random passwords with the length and character sets you choose. Generated locally in your browser — never sent anywhere.
Runs entirely in your browser. Nothing you enter is sent to Nxeon.
A new password on every change
Why use a random password generator?
Weak and reused passwords are behind the majority of account breaches. A generator removes human predictability by drawing every character from a cryptographically secure random source, producing passwords that are practically impossible to guess or brute-force. This tool runs entirely in your browser using the Web Crypto API, so your generated password is never transmitted, stored or logged.
What makes a password strong?
- Length — the single biggest factor; 16+ characters is a good baseline.
- Variety — mixing upper, lower, digits and symbols enlarges the search space.
- Randomness — no words, patterns or personal info.
- Uniqueness — a different password for every account.
Frequently asked questions
Straight answers about how this tool works and what it can tell you.
Are these passwords safe to use?
Yes. They're generated in your browser using crypto.getRandomValues, the same cryptographically secure random source used for security-sensitive work. Nothing is transmitted or logged — the password never leaves your device.
How long should my password be?
For important accounts, aim for 16 characters or more with a mix of character types, giving roughly 100+ bits of entropy. Longer is stronger; the built-in meter shows the estimated entropy as you adjust the options.
What does 'exclude ambiguous characters' do?
It removes easily-confused characters (capital I, lowercase l, the number 1, capital O and zero) so a password is easier to read and type by hand — useful when you'll transcribe it onto another device.
Should I use a password manager?
Yes. The strongest password is one you never have to remember. Generate a long random password here and store it in a reputable password manager, using a unique password for every account.
