About the Wifi Security black outline icon
Three nested wifi arcs rise from a small round dot in the upper left, while a closed padlock with a tall shackle and a keyhole sits at the lower right. The two elements together say the wireless connection is encrypted and password protected, which fits router setup screens, VPN and firewall apps, hotel and cafe hotspot notices, network settings and cybersecurity presentations.
The diagonal arrangement keeps both symbols readable instead of overlapping them, and the padlock body is large enough to hold the keyhole detail. It pairs with wifi off, shield, key and router icons in the library. Use a red or amber tint of the same shape to flag an unsecured network.
This is the black outline version of the wifi security icon: even, monoline strokes that stay crisp at small sizes and suit clean, minimal interfaces, wireframes and light backgrounds.
