A user's online status is an indication of their Misskey usage status. Your online status is displayed as an indicator in the corner of the user icon on your user page and elsewhere.
|🟢 green||online||Misskey is being used right now.|
|🟡 yellow||active||The user is absent but Misskey is still being used.|
|🔴 red||offline||Misskey is not used.|
|⚫ grey||unknown||The status is private or not available for remote users etc.|
Your online status will change automatically and cannot be set manually. You can set your online status to be private.
Some features, such as user suggestions, may be based on online status, so making your status private may make it harder for other users to find you.
