Password Generator

Generate secure, random passwords — everything happens in your browser.

Pick at least one character type
16
664

Your password is generated entirely in your browser using the Crypto API. Nothing is sent to the server.

How it works

  1. Set the length (6-64) and pick the character types you want.
  2. Hit “Generate New Password”; at least one of each selected type is guaranteed.
  3. Copy it to your clipboard with the copy button and paste it where you need.

What actually makes a password strong? Understanding entropy

A password's real strength has little to do with how complicated it looks and everything to do with how unpredictable it is. The way we measure that unpredictability is called entropy, expressed in bits. The more bits of entropy a password has, the harder it is for anyone to guess or crack it.

Two factors raise entropy: the length of the password and the size of the character set you draw from. Both matter, but length matters most. Every single character you add multiplies the total number of possible combinations, so strength grows exponentially rather than little by little. An eight-character password might fall to a determined attacker, while a sixteen-character one becomes effectively unreachable.

Karar Çarkı's password generator lets you choose the length and decide which character types to include: uppercase, lowercase, digits and symbols. Turning on more types widens the pool, so a password of the same length ends up far more resistant.

Your passwords never leave your browser

A fair question to ask of any online generator is: "Does my new password get sent to a server somewhere?" With Karar Çarkı the answer is no. Generation happens entirely on your own device, inside your browser.

That means the passwords produced here are never transmitted across the internet and never stored on a server, by us or anyone else. For a tool whose whole job is security, this is a foundational design choice rather than an afterthought. You could even disconnect from the internet and the generator would keep working, because the computation is local to your machine.

Habits that turn a strong password into real security

Generating a strong password is only step one. Using it well is what keeps your accounts safe. These habits protect you against the most common kinds of attack:

  • Aim for at least 12 characters everywhere, and 16 or more for critical accounts like email and banking
  • Use a completely unique password for every site, so a single breach can't cascade across your accounts
  • Avoid dictionary words, names, birthdays and predictable sequences like "qwerty" or "123456"
  • Store everything in a password manager instead of trying to memorise dozens of strings
  • Switch on two-factor authentication wherever it is offered

The hardest habit for most people is "a unique password per site," and that is exactly why a password manager is so valuable. It remembers all those long, random strings for you, leaving you with just one master password to recall.

Frequently Asked Questions

Is the password secure?

Yes. The browser's cryptographic random generator (window.crypto.getRandomValues) is used to produce truly random passwords.

Is the password sent to a server?

Absolutely not. The password is generated entirely in your browser — never sent to any server, log, or third party.

Which characters are included?

Lowercase, uppercase, digits, and special characters — pick whichever combinations you want. There's also an option to exclude similar characters (0/O, 1/l).

How do I copy the password?

Click the "Copy" button next to the generated password to put it in your clipboard.

Am I supposed to memorise the password the tool gives me?

No, and trying to is the wrong approach. Genuinely strong passwords are hard to remember by design. The healthiest workflow is to save the generated password directly into a password manager and only ever memorise that manager's single master password.

Do symbols really make my password stronger?

Yes, because including symbols enlarges the character set and increases the number of possibilities per position. That said, length has a bigger impact. The ideal password combines both: enough length plus a mix of uppercase letters, digits and symbols.

Can I reuse one strong password across a few sites I trust?

It is strongly discouraged. No matter how strong the password is, the moment one site's database is leaked, every account sharing that password is exposed at once. A unique password per site is the only safe approach.

How long does a password need to be to be unguessable?

Twelve characters is a sensible floor for ordinary accounts. For critical ones such as email, banking and your password manager, prefer 16 or more. Each extra character multiplies the time a brute-force attack would take, pushing it from feasible toward practically impossible.
