The Lock Open 4 icon shows an open geometric padlock with a raised shackle, a two-tone lock body, and a central keyhole. Drawn in the Cyber Duotone style on a 24px grid with a 1px stroke so its sharp geometry stays clear at small sizes. Use it for unlocked access, authentication states, security settings, permissions, and privacy controls. It belongs to Cyber Duotone set in the Cyber family.
