Random Password Generator

Generate strong random passwords with custom length and character sets.

How to use this tool

Set the length and which character types to include.
Optionally exclude ambiguous characters.
Generate (and regenerate) with one click.
Copy the password.

How it works

crypto.getRandomValues() supplies cryptographically secure randomness; characters are drawn from your chosen pools.

Tips

Use a password manager instead of reusing passwords.
Never rely on memory for 16+ character passwords — store them safely.

Limitations

Strength depends on using unique passwords per site; a generator can't fix reuse.

Frequently asked questions

How strong should my password be?

16+ characters mixing upper, lower, digits and symbols is a strong modern default. Longer beats complexity.

Is the password stored or sent anywhere?

No — generation uses the browser's crypto API and everything stays local.

Can I avoid ambiguous characters?

Yes — a toggle removes lookalikes like 0/O and 1/l/I for easy typing.
