QR Codes and Passwords: What to Check Before Sharing
Published
A QR code stores information directly
The generator encodes the text, URL, or Wi-Fi details you enter. It does not require a subscription or create a mandatory redirect. You can save the pattern as PNG or SVG; the vector format is useful for print.
Keep a clear border around the code and test it with a second device. A sharp image and strong contrast help scanners read it. If the code contains a URL, the pattern stays the same even if the destination site later changes or disappears.
A Wi-Fi QR code does not encrypt the password
A Wi-Fi QR code can contain the network name and, when needed, its password. Anyone who can scan the code can recover that information. Share it only with people you intend to give network access.
Local generation avoids sending those details to this site's server. It does not make the resulting QR code a protected secret.
Read before opening
The scanner displays decoded content first; it does not open a link automatically. Check the domain and destination before choosing to open it. A code from an unknown source can lead to a deceptive website.
Images and camera frames are decoded in the browser. The camera stops after a successful scan, when you stop it, or when the page becomes hidden.
A password score is only an indicator
The local checker looks for visible features such as length, repetition, and common sequences. It does not check a breach database and cannot guarantee that a password has never been exposed.
The generator uses the browser's cryptographic randomness and includes the character groups you select. The generated text remains in page memory; copying it deliberately places it on your device's clipboard.
