Strong passwords, generated locally
Pick length and character options and generate cryptographically strong passwords, locally in your browser, never sent anywhere.
For the best results: Use the longest password each site allows, length beats complexity. Generate a fresh one per account and store them in a password manager, never reuse one.
Select at least one character setStrength: Excellent (~123 bits of entropy)
Generated locally with your browser's cryptographic random source, never sent to any server, not even ours. Store it in a password manager, not a note.
What is Password Generator?
Password Generator is a free productivity tool that generates cryptographically strong random passwords locally in your browser, so they are never transmitted anywhere. It runs entirely in your browser, so what you enter is never uploaded, logged, or sent to any server, and it keeps working even offline. No account or subscription is required, and nothing is stored.
- ✦Runs entirely in your browser. Nothing you enter is ever uploaded
- ✦No account, no sign-up, and no data leaves your device
- ✦Works offline once the page has loaded
See it in action
Someone setting up a new email account wants a strong password their manager can store rather than one they memorize.
What you type
Length: 20 Include: uppercase, lowercase, numbers, symbols Exclude look-alikes (l, 1, O, 0)
What you get
Generated locally, never sent anywhere: vT7#kqmR$eZ2bXw9!Ludp Strength: very strong — an estimated 130+ bits of entropy Each refresh draws fresh randomness from your browser's crypto API; copy it straight into your password manager.
Tip: For a password a machine will remember, favor raw length over exotic symbols — a 20-character random string beats a short one with every symbol type, and excluding look-alike characters saves grief if you ever have to read it aloud or type it once.
Use cases
What people use it for
Replace a reused password properly after a breach notification email lands in your inbox.
Generate a fresh, strong Wi-Fi password when you move house or offboard a flatmate.
Create one-off strong logins while setting up accounts for a parent who reuses their pet's name.
Who uses Password Generator?
Anyone opening accounts
creating a unique, strong password for each new sign-up instead of reusing the same one everywhere
IT support staff
handing a new starter a solid temporary password on the spot without emailing anything guessable
Password manager users
generating a random string to save in their vault when their manager is not to hand
How it works
- 1Choose the length and which character types to include.
- 2Your browser generates the password locally using its cryptographic random source. It never leaves your device.
- 3Copy it straight into your password manager; nothing is sent anywhere.
Tips for the best results
- Turn on every character type the site allows, since mixing upper case, lower case, numbers and symbols widens the possibilities.
- Choose the greatest length the site accepts, as length is the single biggest factor in how hard a password is to crack.
- Copy the password straight into a password manager rather than trying to remember or write it down.
- Generate a brand new password for every account, so one leak never puts your other logins at risk.
- If a site rejects certain symbols, switch those off and generate again rather than editing the password by hand.
FAQ
Frequently asked questions
Does the password ever get sent to your servers?
It never leaves your machine. Generation happens inside your browser using its built-in cryptographic random number generator, with no upload, logging or storage anywhere, not even on this site's servers. Once the page has loaded you could switch your connection off and it would keep working, which is exactly the property you want in a password tool.
Why isn't this an AI tool like the rest of the site?
Because AI is the wrong instrument for passwords. A language model produces plausible, pattern-rich text (the opposite of secure randomness) and anything typed into or produced by an AI travels to a server for processing. A password needs to come from a cryptographic random source and be seen by nobody. So this tool deliberately skips AI and generates locally instead.
What actually makes a generated password strong?
Length, above everything. Each extra character multiplies the number of guesses an attacker must make, so a long password of plain letters beats a short one bristling with symbols. Use the longest length the account will accept, include mixed character types when the site allows them, and never trade length away just to make a password easier to type.
If I lose it, can I regenerate the same password?
No, every click produces fresh output from cryptographic randomness, and nothing is remembered, so an identical password can't be reproduced and no record of it exists anywhere. Copy it straight into a password manager before leaving the page. That un-repeatability isn't a flaw; a generator that could replay its output would be one an attacker could replay too.
A site rejected the generated password, what now?
Some sites ban specific symbols or cap password length, usually a sign of dated security practice you can't change. Adjust the character options to drop symbols, or shorten the length, and generate again, a long letters-and-digits password is still strong. Keep the stricter settings for everywhere else; one fussy site shouldn't lower your standards across the board.
How long should my password be?
Longer is stronger. General security guidance is at least twelve to sixteen characters, and length protects you more than swapping in a handful of symbols. Here you choose the length, so set it as high as a site will accept and let the random mix of characters do the hard work.
Should I use a different password for every account?
Yes, always. If you reuse one password and a single site is breached, attackers can try it everywhere else. A unique random password per account contains the damage to just that one login. Generate a fresh one here for each sign-up and store them in a password manager.
Can I use this to generate a passphrase or PIN?
You control the length and which character types are included, so you can produce a short numeric PIN or a long, complex string. It builds random character passwords rather than word-based passphrases. Everything is generated locally in your browser, so whatever you create is never transmitted or saved by the site.
Are there any usage limits?
None. Everything is generated locally in your browser, so there is no server cost, no metering, and no daily cap, use it as many times as you like, completely free.
