Your passwords never leave this page.
KeyMint is a static page that runs a generator in your browser. There is no account to create, no server that sees your passwords, and nothing kept after you close the tab.
What KeyMint does
- Generates every password locally using the Web Crypto API.
- Bundles its word lists with the page, so no network request is needed to generate.
- Keeps generated values in the page's memory only.
- Analyses any password you paste into the checker on your own device.
What KeyMint never does
- Send a generated or pasted password anywhere — no server, no API, no breach check.
- Store passwords in local storage, session storage, IndexedDB, cookies or a database.
- Keep a history of what you generated, in this session or any other.
- Put a password in a URL, a query string or a shareable link.
- Include generated content in analytics, error reports or logs.
Analytics
If usage analytics are enabled on this site, they record only generic interactions — that a generator was opened, which mode was selected, that the copy button was used. They never include a generated password, the words chosen, a PIN, a custom character set, a prefix or suffix, or anything you typed into the checker.
Clipboard
Copying puts the password on your system clipboard, which is outside KeyMint's control. The optional clipboard clear tries to overwrite it after the time you choose, but browsers only permit that while this page is open and focused. If you switch apps or close the tab, KeyMint cannot clear it — so treat the feature as a convenience rather than a guarantee.
Exports
When you generate several passwords at once you can download them as a TXT or CSV file. That file is a plain list, created in your browser and saved by you. Store it securely, move the passwords into a password manager, and delete the file when you are done.
Word lists
Passphrases use the Electronic Frontier Foundation's diceware word lists, bundled with the application and used under the Creative Commons Attribution 3.0 United States licence. Hyphenated entries are removed so that separators stay unambiguous, and the entropy KeyMint quotes always reflects the exact number of words available after your filters.
