Bonus Keys

Bonus Keys are special items that are given to you at random upon A-Rank clearing or higher a Featured Quest.
You can only receive one item per Featured Quest Ship wide and you're not always guaranteed a key.
Most Bonus Keys expire 168 hours from the time it was obtained, however, Bonus Keys from campaigns often have different expiration durations,
such as a month from when it arrives in the mailbox.
