About the Wifi Security Padlock black outline icon
Three widening wifi arcs rise above a dot, and a closed padlock with a keyhole sits on the right, overlapping the outer waves. The combination means an encrypted connection, a protected hotspot or a password-locked router rather than plain connectivity. Use it in VPN apps, network setup wizards, guest wifi notices, cybersecurity landing pages and IT service slide decks.
The padlock body is solid and rectangular against the thin curved arcs, giving strong contrast that survives scaling; the arcs are cropped where the lock covers them so the layering stays clear. Pair with firewall, shield and router icons, and avoid sizes under 24 px where the keyhole closes up.
This is the black outline version of the wifi security padlock icon: even, monoline strokes that stay crisp at small sizes and suit clean, minimal interfaces, wireframes and light backgrounds.
