About the Lock black outline icon
This icon shows a closed padlock with a smooth rounded shackle and a keyhole cut into the body, a universal symbol of security, privacy, and restricted access. It fits login screens, password fields, settings menus, terms-and-conditions banners, and packaging that highlights data protection.
The design is a single rounded body topped by a thick arched shackle, with a simple keyhole shape centered below for balance. It pairs well with key, shield, and fingerprint icons in the same set. At small sizes, the bold keyhole keeps the icon readable even below 24px.
This is the black outline version of the lock icon: even, monoline strokes that stay crisp at small sizes and suit clean, minimal interfaces, wireframes and light backgrounds.
