About the Key black filled icon
A large circular bow with a small hole at its upper left joins a straight shaft that runs diagonally to the lower right, ending in a blade with three stepped notches and an angled tip. It reads instantly as access, unlocking and credentials, which makes it useful for login and password fields, API key and license pages, account security settings, hotel or rental booking apps, and locksmith and real estate sites.
The diagonal placement fills the square frame corner to corner, giving the key a longer blade than upright versions and clearer tooth detail. It pairs with lock, shield, fingerprint and door icons in the library. Keep it at 24px or larger so the notches remain distinct.
This is the solid black filled version of the key icon: a bold silhouette that reads clearly at 16-24 px and on dark or busy backgrounds, and prints well in one colour.
