How to Make a WiFi QR Code (So Guests Never Ask for the Password)

Reading a long, random WiFi password aloud to every guest gets old quickly. A WiFi QR code solves it: point a phone camera at the code and the phone offers to join the network. Modern iPhones (iOS 11 and later) and most Android phones (Android 10 and later, and many older ones via the camera or Google Lens) support it.

WiFi QR codes eliminate the need to read lengthy passwords aloud to guests. iPhones (iOS 11 and newer) and many Android phones (Android 10 and later, some older models via camera or Google Lens) can scan these codes. The code consists of simple text following a standard format. To connect, the phone reads this text and configures the WiFi settings accordingly.

Security type (WPA for WPA2 and WPA3 networks, WEP or nopass for open networks) and network name (SSID) are specified. Hidden networks can be marked but are not required. Special characters must be escaped with a backslash. If a scan fails, the issue is usually unescaped characters. To create a code, use a browser-based generator that doesn't upload your data or send your password.

Generate and test the code on your own device before printing. Print it at a readable size, ideally near the router location. The code holds your password in plain text, so sharing it is as risky as sharing the password itself. Use a guest network and change the password if it becomes widespread. Include the SSID next to the code for devices that can't scan.

Unix Timestamps Explained: Seconds, Milliseconds, and Time Zones

A Unix timestamp (also called epoch time or POSIX time) is the number of seconds that have passed since 00:00:00 UTC on 1 January 1970, a moment known as the Unix epoch.

  • Unix timestamp represents seconds since 1970 epoch
  • Seconds vs milliseconds differentiated by number length
  • Store timestamps in UTC to avoid Year 2038 problem

How to Check Color Contrast for Accessibility (WCAG Explained)

Low-contrast text is one of the most common accessibility failures on the web, and one of the easiest to fix. It affects people with low vision and color-vision differences, but also anyone reading a…

  • WCAG quantifies contrast via ratio measuring luminance between colors.
  • Level AA requires minimum 4.5:1 contrast ratio for normal text.
  • Non-text elements like input borders need a minimum 3:1 contrast.

How Strong Should a Password Be? Length vs. Complexity

Password strength is really a question of how many guesses an attacker would need. Every extra character multiplies that number, which is why length matters far more than swapping an a for an @.

  • Length of password exponentially increases possible guesses for attacker
  • Entropy measures password unpredictability in bits, doubles with each bit
  • Passphrases made of random words offer strong security and memorability
