Generate QR codes, passwords and more

Choose by task

Generators create a new value: a credential, a scannable code, a randomized choice, or an event layout. Pick the tool by what will consume the result. Generation happens on your device, but you remain responsible for storing secrets safely and controlling how exported images, links, and lists are shared.

Create credentials and test values

Use Password Generator for real credentials, Password Strength to review a candidate, Test Data Generator for development fixtures, and Secret Note when you need local encryption rather than plain text.

Create something a device can scan

Use the general QR tool for URLs and text, Wi-Fi QR for network settings, Contact QR for vCard details, and Code 128 Barcode for compatible product or inventory strings.

A reliable workflow

Decide who or what will consume the result.
Use examples or dummy values to check the output format.
Generate the real result and test scannable output on a separate device.
Store credentials in a trusted manager and review the sharing scope of exported files or printouts.

Before you start

Use a unique password for every service and avoid reuse.
QR readability changes with color, quiet zone, size, and print quality; test the final medium.
A browser-based random draw is not a guarantee of fairness for regulated, legal, or high-value decisions.

Frequently asked questions

Are generated passwords stored by Benri.dev?

No. Generation happens in your browser and the password is not stored on Benri.dev's servers. Save it promptly in a trusted password manager rather than an unprotected note or screenshot.

Will a generated QR code work forever?

The image itself has no expiry, but its URL, Wi-Fi settings, or contact details can become outdated. Keep the encoded destination available and update distributed material when the underlying information changes.
