About the Authentication User Key black outline icon

A simple user avatar built from a circular head and a dome-shaped body carries a key laid over its chest, the tapered key head with its small hole sitting on the torso and the notched blade extending below. It reads as proving who you are, so it suits login and sign-up flows, password managers, two-factor prompts, admin permission settings and account recovery pages.

The figure and key share one axis, so the blade continues the vertical center line and holds the mark together. Proportions are generous: a wide body, a large head and a key that stays readable at small sizes. Use it alongside fingerprint, shield and user profile icons, and keep it 24 px or larger so the key notches survive.

This is the black outline version of the authentication user key icon: even, monoline strokes that stay crisp at small sizes and suit clean, minimal interfaces, wireframes and light backgrounds.
