A smartphone in the shape of a triangle.

The HTML5 Logo.

This provides clear visual separation between logical groups. But there are a couple of problems. Firstly, the separator character may not be interpreted correctly by screen readers. They may read out "Vertical Pipe",…

Screenshot of a network inspection panel. Dozens of JPEG images are being downloaded.

Strange Encoding Errors in TOTP QR Codes

A QR code.

Not really a security issue, but one which I thought was worth highlighting. It shows the peril of slightly vague specifications. When you scan a 2FA token into your authenticator app via QR code, you get presented with a bunch of information about your account. This lets you store things like the issuer and the account name.
