Password Generator
Create strong, random passwords instantly with this free online tool. It is ideal for developers, IT admins, and everyday users protecting their digital accounts. Use it anywhere you need to generate complex and unguessable credentials.
How the Password Generator works
- 1
Add Your Content
Drag Length anywhere from 6 to 128 and tick the character classes you want — lowercase, uppercase, digits, and symbols are all on by default, plus an optional filter that drops look-alike pairs like I, l, 1, O, and 0.
- 2
Built with a guaranteed mix
The tool draws random characters from your enabled pools, then shuffles — and it deliberately includes at least one character from every ticked class before filling the rest, so a 20-character password never accidentally skips symbols.
- 3
Get Your Results
View the generated password with its approximate entropy and estimated crack time underneath. Copy it straight into registration forms or your password manager.

Password Generator FAQ
Do I need to create an account?
No, you can use this tool immediately without signing up or logging in.
Is my data secure and private?
Yes, all processing happens directly in your browser, so no data is ever sent to our servers.
Does it work offline?
Once the page is loaded, the core logic works offline since it runs locally in your browser.
Is there a character or size limit?
Length runs from 6 to 128 characters. That ceiling covers every practical use; longer strings mostly annoy the humans and forms that have to paste them.
What does the ambiguous-character option do?
It removes I, l, 1, O, lowercase o, and 0 from the pool — characters that look nearly identical in many fonts. Handy for passwords you will read aloud or type from a printout; leave it off when maximum pool size matters more.
How is it different from similar tools?
Generation runs entirely in your browser as local JavaScript — there is no account step and nothing is uploaded, and every password guarantees at least one character from each class you ticked.
What is the technical working principle?
It draws random characters from your enabled pools, seeds one character per ticked class so none go missing, shuffles with a Fisher-Yates pass, and reports the entropy of what it produced.
What is a common use case?
Users use it daily to create strong, unique passwords for new website registrations and account updates.
