Frequently Asked Questions
Are generated passwords stored on WebTools servers?
Never. Passwords are generated using the browser's crypto.getRandomValues API locally on your device.
Can QR codes generated here expire?
No, static QR codes directly encode your data into the matrix patterns, meaning they will work forever without redirection servers.
