About the No Lock Sign color outline icon
A closed padlock with a rounded shackle and a square body sits inside a large circle that is cut by a single diagonal bar, the standard prohibition mark.
The pairing reads as no lock, unsecured connection or protection disabled. Use it in browser and network security warnings, permission screens, IoT device status lists, workplace safety signage and infographics contrasting secure and insecure setups.
This is the colour outline version of the no lock sign icon: the same line drawing in an accent colour, useful for highlighting a state, a category or a brand tone without adding visual weight.
