A motto is a short description of your squad. Think of it as your catchphrase or slogan. It can be seen by players who are searching for a squad, so it can be a good recruiting tool! Your motto can have up to 60 characters.
If you’re the leader of the squad, you can add or edit your motto. This is done by tapping the pencil icon on the squads page and then tapping the pencil icon beside squad motto.
