🔑 Key

A key, which may be used to open a door or lock. Shown on most platforms in gold (yellow), but also sometimes as bronze, or silver.

DJ Khaled displays the key emoji on Snapchat for verification.

This emoji does not show in the title bar of Safari, presumably to prevent less-reputable sites pretending to be secure (encrypted using HTTPS) when they are not.

Key was approved as part of Unicode 6.0 in 2010 and added to Emoji 1.0 in 2015.
