Becoming best friends with another player outside of your Animal Crossing: New Horizons game is a great way for the two of you to work together on a singular island. When you visit an island in multiplayer or have a friend to check on yours, you can make them a best friend.
To make someone a best friend, you first need to open your NookPhone and add them to your best friends list in the smartphone app. You can see any player you have interacted with and from this list you can choose which ones you want to make a best friend with. You don't need to type their name, add their Nintendo friend code, or have any additional information. It makes the game's multiplayer and cooperative mode a seamless experience.
When you make another your best friend in Animal Crossing they can freely modify and edit parts of your island. By default, whenever you invite another person to visit your island, they don't have this ability. For anyone you want to see longer, but don't stay too long, you probably don't want to give them access to change the way you have things. They might do something by mistake, or worse. When you make someone your best friend, you have to make sure you choose wisely and think about that decision.
Once you know how to tag another player as a best friend, things should become a lot easier to complete in the game as you roam an island together. Those who aren't your best friend have limited access to what they can do while visiting your island.
