An online password generator can be safe, but only if it is built with privacy in mind. The most important question is simple: does the password stay in your browser, or is it sent somewhere else?
This guide explains what to check before using any password generator for real accounts.
Look for browser-only generation
A safer password generator creates the password on your device, inside your browser. It should not send the generated password to a backend, save it in a database, place it in analytics, or add it to the URL.
The Pass Key uses the browser crypto API for generation and does not use Math.random() for password creation.
- No generated passwords sent to a server.
- No password history.
- No localStorage, cookies, analytics, or URL query strings for generated passwords.
Avoid generators that require an account
You should not need to create an account just to generate a random password. If a generator is part of a password manager, saving the password may require an account, but the generation step itself should still be clear and private.
For The Pass Key, there is no account system and no password vault. Generate the password, copy it, and save it in your own trusted password manager.
Check the randomness source
Password generation should use cryptographically secure randomness. In modern browsers, that means `window.crypto.getRandomValues()`. Basic random functions are not designed for security-sensitive password generation.
This is especially important for random passwords, PINs, and passphrases.
Be careful with strength checkers
A strength checker should also run locally. Do not paste real passwords into unknown tools that send the value to a server.
A safe checker can estimate length, variety, repeated characters, and common weak patterns without transmitting the typed password.
Practical examples
- Safe sign: the page clearly says passwords are generated in the browser.
- Risk sign: the generated password appears in the URL.
- Risk sign: the tool requires signup before showing a password.
- Safe habit: generate the password, save it in a manager, then close the page.

FAQ
Can a website see a generated password?
It depends on how the tool is built. Browser-only tools can generate passwords locally without sending them to the website server.
Does The Pass Key store generated passwords?
No. Generated passwords are not stored, logged, transmitted, placed in analytics, or saved in browser storage.
Should I save generated passwords somewhere?
Yes. Save each unique password in a trusted password manager so you do not reuse or forget it.
Conclusion
Online password generators can be useful, but privacy matters. Use tools that generate locally, avoid storing passwords, and explain their security model clearly.
After generation, store the password in a trusted password manager and use a different password for every account.
