Use Nintendo Account on multiple consoles?

I own a Nintendo Switch, which unfortunately is a bit uncomfortable in handheld mode because it is a little curved. The left joycon is also defective. That's why I always play in Dock mode with my Pro Controller and really enjoy it. (My guarantee is over btw)

Somehow I missed playing in handheld mode, so I thought about buying a Switch Lite.

My question is: Can I use my Nintendo Account on both devices? For example, I play Zelda in Dock mode with my Switch and then I continue to play in Handheld mode with my Switch Lite. Is that possible?

Yes this is possible.

One console is set as the main console on which it is possible to play at any time. Additional consoles need a constant internet connection to play. If a game is started on the main console, the game is paused on the other console. If you want to use the game saves between the consoles you need nintendo online
