About these generators

Generators create something new on demand: a strong password, a QR code for a link or Wi-Fi network, a barcode, a random number or a fair pick from a list. Where security matters, these tools use your browser’s cryptographic random number generator rather than a predictable one.

Results are created on your device and are never stored or transmitted, so a generated password stays private from the moment it appears.
