2FA solution that works with sma 500v but without smart device
Hi, I'm new to the community. With recent alerts from SonicWall, I've enabled 2FA for VPN access on our SMA 500v. However, some of my users are in areas where smart devices are not allowed. Does anyone know of a 2FA solution that works with SonicWall VPN and does not require a smart device? Thanks in advance.
