Strong Password Generator — Secure Random Passwords (Free)

Generate strong random passwords online for free. Build secure passwords with custom length, character sets and strength indicator — all in your browser.

All tools run in your browser — nothing you process is ever uploaded.

How to Use

Set the length of the password you need.
Choose which character sets to include: lowercase (a-z), uppercase (A-Z), digits (0-9) and symbols (!@#…).
Optionally enable Exclude ambiguous to drop easily confused characters like 0, O, 1, l and I.
Press Generate to produce a random password. A strength indicator rates it, and you can copy it straight away.

Passwords are generated entirely in your browser, so they are never transmitted, logged or stored anywhere. The character-set choices also change the strength rating, since including more types and a longer length both increase the space of possible passwords.

Always save a generated password in your password manager as soon as you use it — the tool intentionally does not store anything, so it cannot show it to you again later.

Tips

Length matters more than complexity. A 16-character password drawn from all four character types is substantially stronger than a short one, even one full of symbols. For most accounts, 12 to 16 characters is a sensible range. Reusing a password across sites is the biggest risk, so generate a fresh one for each account.

You should also generate both a human-friendly version (with ambiguous characters excluded) for anything you have to type by hand, and a longer all-inclusive version for services where you will rely on your password manager.

Why use it

Weak or reused passwords are the most common route into compromised accounts. A random generator removes the temptation to pick something memorable but predictable. Because it runs locally and stores nothing, it is also private — no third party ever sees the credentials you create. Generating a strong password takes one click and works for free.

FAQ

How do I generate a strong password?

Set the length you want, tick the character types to include (lowercase, uppercase, digits, symbols), and press Generate. The tool shows a strength rating and lets you copy the result. Everything runs locally, so the password is never sent anywhere.

How do I create a password that is hard to guess?

Use a longer length — 12 to 16 characters — and include a mix of uppercase, lowercase, digits and symbols. Longer random passwords are far stronger than short ones that reuse familiar words. You can also exclude ambiguous characters like 0, O, 1, l and I.

Can I avoid confusing characters like 0 and O?

Yes. Switch on "Exclude ambiguous" and the generator removes 0, O, 1, l and I from the output, so the password is easier to read and type without mistakes.
