Frequently asked questions
Are these guides a substitute for professional security advice?
No. They provide practical general education for password and account hygiene, not legal, financial, or incident-response advice.
Why are some guides about browsers and Web Crypto?
PwdGen is a browser-local tool, so the security boundary depends on modern browser randomness, local execution, and the limits of the user device.
Why do the guides link back to tools?
Each guide links to the relevant local tool so readers can apply the recommendation without sending passwords to a server.
