What Does This Mean?
A private social media account whose posts can be seen only by approved followers, literally "lock account". It is typically a personal or hobby account used by a small circle; the counterpart is a public account (公開アカウント). Often shortened to 鍵 or 鍵アカ.
REAL-WORLD EXAMPLE
""She made her account a 鍵垢 so that only close friends could read her posts.""
LORE & ORIGIN
Short for 鍵アカウント or 鍵つきアカウント, from the idea of locking an account so outsiders cannot see in. Weblio describes it as a nickname that settled among users rather than an official feature name, notes that it spread mainly on X and similar services, and says people usually lock an existing account rather than create a new one. Dated first use is not documented. The label itself is neutral.
