How to Create a Strong Password
- Drag the Length slider — 16 characters is a good default, use 20+ for important accounts.
- Leave all four character types switched on for the widest possible pool of characters.
- Click Generate Password, then Copy and paste it into your password manager.
A strong password is long and unpredictable. This tool builds every password from a cryptographically secure random source in your browser, so the results cannot be guessed or reproduced. Nothing is uploaded, logged or stored.
Password Security Tips
- Use a password manager. It is the only practical way to keep a different password for every site.
- Never reuse a password. One breach then exposes every account that shares it.
- Longer beats complicated. Twenty lowercase letters take far longer to crack than eight mixed characters.
- Turn on two-factor authentication for email and banking, even with a strong password.
- Change passwords after a breach — and anywhere you had reused the leaked one.
How Long Should a Password Be?
Length is the single biggest lever you control. Every extra character multiplies the number of guesses an attacker would need, which is why a long plain password beats a short complicated one.
- 16 characters — a good working default for everyday accounts
- 20 or more — sensible for email, banking and anything that can reset other passwords
- 12 characters minimum — the floor for sites that cap how long a password may be
Slide the length control on this page and the generated password updates straight away.
Passwords, Passphrases and Password Managers
A password manager is what turns strong generation into a habit. Let it hold one long random string per site, and you are left with a single thing to remember — the master password for the manager itself.
Random strings with three or four character types suit websites; longer human-memorable passphrases suit the master password. Whichever you choose, the same rule applies: never share one password between two accounts.
Password Mistakes That Undo a Strong Password
A generated password only helps if the rest of the habit holds up. Four common slip-ups cancel most of the benefit:
- Reusing one password across several sites
- Writing it in a plain note or a chat message to yourself
- Choosing a short password because a site feels low risk
- Sharing an account and its password with somebody else
Fix those four and a random sixteen-character password does the job it was generated for.
Frequently Asked Questions
How do I create a strong password?
Use a long password of 16 characters or more that mixes uppercase letters, lowercase letters, numbers and symbols. This generator does that automatically — set your length and character options, then click Generate.
Is this password generator safe to use?
Yes. Passwords are created locally in your browser with the Web Crypto API (crypto.getRandomValues), a cryptographically secure random source. Nothing is ever sent to a server, logged or stored anywhere — close the tab and the password is gone.
How long should my password be?
Aim for at least 16 characters for everyday accounts, and 20 or more for email, banking or anything you would hate to lose. Length matters more than complexity: every extra character multiplies the number of guesses an attacker needs.
What is a password generator free to use for?
Everything. This password generator is free with no sign-up, no download and no limit on how many passwords you create. Use it for new accounts, password resets, Wi-Fi keys, guest logins or anywhere you need a random string.
Can I generate multiple passwords at once?
Yes. Click Generate as many times as you like — each click produces a brand new random password, and the strength meter updates with every result. Copy the one you want and generate the next.
Are the generated passwords sent anywhere?
No. Every password is built inside your browser the moment you press the button, so nothing is transmitted, logged or stored, and the page keeps working with the network disconnected.
Should I use symbols in every password?
Only if the site accepts them. Including symbols widens the pool of possible characters, which makes a password harder to guess, but a longer password without symbols can still be stronger overall.
What should I do after a data breach?
Change the password on the affected site first, then change it anywhere you had reused the same password. That second step is the one most people skip, and it is the one that limits the damage.
