The Lock Open 4 icon shows an open angular padlock with a hexagonal body, raised shackle, and centered keyhole, with one side softly filled in a second tone. Drawn in the duotone style on a 24px grid with a 1px stroke so it keeps the sharp geometry clear at small sizes. Use it for unlocked access controls, password states, account security, permissions, and authentication interfaces. It belongs to Cyber Duotone - Free set in the Cyber family.
