Lost 2FA on remote device?


Hi, I have a Linux/Debian installed in my summerhouse so I can monitor stuff, and configure my router etc, it has worked fine for months. I have used 2FA so this remote, so when connecting to the PC, I approve connection from my Telephone.

But now, I can connect to PC, but I am not asked to approve on the phone anymore, and therefore my home PC does not connect. I have still SSH connection to my Debian.

What can I do to ensure 2FA will ask for connection again? I can not visit my summerhouse in near future, so I really need to connect from home again.
