If you've ever reused "Password123" across a few accounts, those accounts are the first ones to fall when any one site gets breached. Strong passwords sound complicated, but a good generator gets you a genuinely strong one in seconds.
Why every password needs to be different
If a password leaked from one site gets reused elsewhere, a single breach puts every other account using that password at risk too. This is called credential stuffing, and a large share of real-world account takeovers happen exactly this way — not because the second site itself was hacked, but because the password was recycled. Using a unique password per account removes most of that risk by itself, even before considering anything else about password strength.
How to generate a password with Dagochim
- Open the Password Generator tool.
- Choose between a random password or a passphrase (word combination).
- For random, adjust length and whether to include uppercase, lowercase, numbers and symbols. For a passphrase, adjust the number of words.
- Turn on "exclude similar characters" (like 0/O or 1/l) if you'll ever need to type or copy it by hand.
- Copy the result, and check the strength meter and optional breach-check result.
Random passwords vs. passphrases: what's the difference?
A random password mixes uppercase, lowercase, digits and symbols, so it's strong even at a short length, but essentially impossible to memorize. It's best suited for accounts you'll store in a password manager and rarely type by hand. A passphrase strings together several unrelated words, like "acorn-harbor-velvet-cactus-tulip". With enough words (5-6 or more), a passphrase becomes just as resistant to guessing as a random password, while being dramatically easier for a human to remember or type correctly on the first try. This particular generator can also romanize Korean word lists into their raw two-set keyboard keystrokes (e.g. 사랑 becomes "tkfkd"), which some Korean-keyboard users find easier to recall and type than literal Hangul.
Why length and character variety matter
The time it takes to crack a password through guessing or brute force scales exponentially with both its length and the number of possible characters at each position. In practice, adding one more character to the length usually strengthens a password more than adding one more symbol to an already-decent character set. As a general rule, aim for at least 12 characters for anything routine, and 16 or more for accounts that really matter (banking, primary email, password manager master password).
What the breach-check feature actually does
This tool can optionally check the password you just generated against Have I Been Pwned's "Pwned Passwords" database to see if it's already known to be compromised. It does this without ever sending the real password: only the first 5 characters of the password's SHA-1 hash go to the API (a technique called k-anonymity), and the rest of the comparison happens entirely inside this browser. That means the service checking the hash has no way to learn what the actual password is.
Is my data safe?
Yes. Password generation itself happens 100% inside this browser and is never transmitted anywhere. Only when you explicitly enable the breach-check feature does a partial hash (described above) leave the browser. Once you copy a generated password, store it somewhere safe (ideally a password manager), and avoid leaving it visible on screen if you step away.
Common problems and how to fix them
- A site rejects certain symbols: allowed symbol sets vary by site. Narrow the symbol options in the generator, or switch to a letters-and-numbers-only configuration and regenerate.
- The password is too long for a site's input field: some older sites cap password length. Shorten it, but compensate by maximizing character variety instead.
- A passphrase is hard to remember: reduce the word count, or turn off the keyboard-romanization option to get the words in their original form instead.
- Breach checking feels slow: it's making a request to an external API, so a few seconds of delay depending on your connection is normal. Skip the check and use the password directly if you're in a hurry.
A word on password managers
A generator solves the problem of creating a strong password, but remembering dozens of unique random strings is a separate problem entirely, and that's exactly what a password manager is for. Most modern browsers and operating systems include a basic built-in password manager, and dedicated third-party managers add features like cross-device sync, secure notes, and breach monitoring. The practical workflow most security guides converge on is: use a password manager to generate and store a unique random password for every account that supports it, and reserve memorable passphrases for the handful of cases where you genuinely need to type a password from memory, such as your device lock screen, your password manager's own master password, or a Wi-Fi network you'll be typing on other devices.
Two-factor authentication matters as much as password strength
No password, no matter how strong, protects an account if someone obtains it through phishing, a leaked database from an unrelated breach, or malware on a shared device. Turning on two-factor authentication (2FA) — a second check via an authenticator app, a hardware key, or at minimum a text message — closes that gap, because a stolen password alone is no longer enough to log in. If a site offers 2FA, enabling it provides more real-world protection than squeezing a few extra characters into an already-strong password. Think of a strong unique password as the first layer and 2FA as the second, independent layer; together they cover most of the common ways accounts actually get compromised.
Frequently asked questions
Does this tool store or send the password it generates?
No. The password is generated entirely inside this browser and is never sent anywhere. The only exception is the optional breach-check feature, which sends just the first 5 characters of the password's SHA-1 hash to an external API (k-anonymity), never the actual password, so the real password can't be reconstructed from what's sent.
Is a random password or a passphrase more secure?
At comparable lengths, both are secure enough. A random password packs more strength into fewer characters but is hard to memorize. A passphrase (several unrelated words strung together) is easy to remember and, with enough words (5-6 or more), becomes just as strong as a random password. Pick a passphrase if you'll type it manually often, and a random password if it'll live in a password manager.
How is this different from a password made with Math.random()?
This tool uses the browser's cryptographic random number generator (crypto.getRandomValues) instead of Math.random(). Math.random() can have predictable patterns that make it unsuitable for security purposes, while crypto.getRandomValues produces output that can't be predicted, which is exactly what's needed for passwords or security tokens.
