Using two-factor authentication with Remote Desktop

Remote desktop requires two-factor authentication because it only relies on usernames and passwords by default, and is susceptible to brute-force cracking and password leakage, especially when exposed to public networks. With two-factor authentication (2FA), it is difficult for an attacker to bypass layer 2 verification, such as SMS verification codes, dynamic codes, or hardware tokens, even if the password is stolen. Implementation methods include: 1. Use third-party remote desktop software that supports 2FA, such as AnyDesk and TeamViewer; 2. The enterprise environment can cooperate with NPS and RADIUS servers such as DuoSecurity or Microsoft NPS extensions; 3. Azure virtual machine users can enable MFA in combination with AzureAD. Individual users recommend using the remote control with built-in 2FA function directly.
