Free Local Password Generator (100% Client-Side, No Tracking)
KGEN generates strong passwords entirely in your browser. No tracking, no storage, no server. If you close the page, the generated passwords are gone.
Why Use a Local (Offline) Password Generator?
A local password generator runs entirely on your device. That means the password is created inside your browser without being transmitted to a remote server. This reduces exposure to network interception, third-party logging, or unexpected data retention. If you care about privacy, a client-side tool is a practical baseline: you can generate strong passwords even when traveling, using public Wi-Fi, or working in restricted environments where you do not want any sensitive strings to leave your device.
KGEN is built around a simple principle: no tracking, no storage, no server. You do not create an account. Nothing is uploaded. Closing the page removes generated results from the UI. This model is especially useful when you want to generate passwords for email, banking, or identity-related accounts while keeping the workflow as local as possible.
Readable Strong Passwords: Grouped Format vs. Passphrases
Random passwords are usually the strongest, but many users struggle to read or type them correctly. KGEN supports a grouped A9b format that avoids ambiguous characters (like 0/O or 1/l) while keeping randomness high. By splitting a password into short groups with a separator, you get a balance between strength and usability. For example, a grouped password is easier to read aloud, easier to retype, and less likely to produce mistakes during login.
If you prefer memorability, KGEN also offers word-based passphrases.
Passphrases can be long, easy to remember, and still strong when you use unique combinations and enough words.
When possible, use a clear separator such as - or @ for better readability.
How KGEN Estimates Strength (Entropy)
Strength indicators can be misleading if they assume character sets that are not actually used. KGEN uses a conservative entropy estimate based on the characters present in the generated password. Entropy is a rough way to describe how many guesses an attacker might need. The crack-time label is shown as a simplified offline attack estimate and should be treated as guidance, not a promise.
Real-world security also depends on how you store passwords, whether you reuse them, and whether your device is compromised. The best practice is: use unique passwords for each important account, keep them in a trusted password manager, and enable multi-factor authentication (MFA) whenever possible.
Compatibility Notes (Symbols and Websites)
Some websites restrict symbols. If you run into “invalid character” errors, choose a separator from the
Common group (such as -, @, _, !, $)
or select “None”. This improves compatibility while keeping passwords strong via length and randomness.
Privacy Model: What KGEN Does Not Do
KGEN does not run a backend service for generation. It does not store generated passwords. It does not track clicks or user behavior. It does not send analytics events. The generator logic runs locally so you can use it even offline. If you want an extra layer of assurance, you can download the HTML package and run it entirely offline.
FAQ
Is KGEN really 100% client-side?
Yes. KGEN runs entirely in your browser. No passwords are sent to any server, and there is no account system, database, or remote logging.
Does KGEN store or track anything?
No. KGEN does not store generated passwords, does not track user behavior, and does not send analytics events.
What password formats does KGEN generate?
KGEN supports grouped passwords (A9b units with separators), word-based passphrases, and numeric PIN-like passwords.
How does KGEN estimate strength?
KGEN uses a conservative entropy estimate based on the character sets actually used in the generated password. The estimate and crack-time display are rough offline-attack guidance, not a guarantee.
Is a local/offline password generator safer than online tools?
Often yes. A local generator reduces the risk of data leaving your device. However, your overall security still depends on your device integrity and how you store and reuse passwords.
