Generating Secure Passwords, QR Codes and Placeholder Data

Strong passwords, scannable QR codes, and realistic placeholder text are everyday needs for developers, designers, and regular users alike. The quality of a generator matters: a weak password generator undermines account security, and a poorly configured QR code can fail to scan.

The Password Generator and Random Number Generator use a secure random source, so results cannot be predicted. The QR Code Generator supports different error-correction levels, and Lorem Ipsum gives classic placeholder text for mockups.

Key Things to Know

  • Truly Random: Passwords and random numbers use a secure random source, not a simple predictable one.
  • Configurable QR Error Correction: Choose higher error correction for QR codes that will be printed small or may get partially obscured.
  • Nothing Logged: Generated passwords and data are never transmitted or stored — each generation happens fresh in your browser.

Common questions about this category's tools, accuracy, and privacy.

It uses a secure random source built into your browser, which is suitable for strong, unpredictable passwords.
No. Passwords are created on your device and are never sent or saved anywhere.
They control how much of the QR code can be damaged or obscured while remaining scannable — L (~7%) offers the least redundancy and H (~30%) the most, at the cost of a denser code.
It's traditional filler text used by designers and developers to preview layout and typography without the distraction of meaningful content.
Yes. The Random Number Generator lets you set a minimum and maximum value for each generated number.
