Commonly used for content concerning safety, security, privacy, and protection as well as various senses of lock, e.g., locked in/down. As such, it can be used to encapsulate the slang phrase “locked in,” to convey intense focus, commitment, or full mental engagement on a task or goal.

This emoji does not display in page titles on Apple’s Safari web browser, presumably to prevent less reputable sites from pretending to be secure (encrypted using HTTPS).

Additionally, this emoji is not supported in Twitter / X names, to minimize confusion with private accounts on the platform. Learn more here.
