While it’s possible to transfer user and save data between Switch consoles, you cannot share save data between different user profiles. In other words, if you’re playing Legend of Zelda: Breath of the Wild on one user profile, you can’t copy your save file to another player’s profile. You can, however, access your games and save data via your user profile across multiple consoles, so long as they’re linked to your Nintendo account. Each Switch can have up to eight Nintendo accounts and user profiles associated with it. While your Nintendo account can be linked to multiple Switch consoles, only one can be your primary system. When playing on a non-primary system, you must be connected to the internet to play titles you’ve downloaded unless you have the game data saved to an SD card. Since the Switch Lite is meant to be played on-the-go, consider making it your primary device so you don’t have to worry about finding a Wi-Fi connection.
