Authentication User Key black filled icon

About the Authentication User Key black filled icon

A simple user avatar with a round head and shoulders sits behind a large horizontal key whose circular bow overlaps the figure and whose toothed blade runs to the right edge. The combination reads as identity verification, account access and login permission. Use it for sign-in and two-factor screens, password manager apps, admin role settings, user permission tables, and security sections of a SaaS marketing site.

The key is drawn at nearly the same scale as the person, so neither element dominates, and the small hole in the bow keeps the classic keyhole cue. The avatar silhouette matches the user, profile and team icons elsewhere in the library. Use 32px or larger so the key teeth do not blur into a solid bar.

This is the solid black filled version of the authentication user key icon: a bold silhouette that reads clearly at 16-24 px and on dark or busy backgrounds, and prints well in one colour.
