Is there any possibility to make Two-Factor Authentication (2FA) feature for VPN connection ?  (similar like new 2FA feature for Cloud Access)

I mean: when a user wants to establish VPN connection with his PC into company network (OC200 and ER7206 or ER605) ,  need to use 2FA  for example via Google Authenticator. 

It should be independent of the type of used VPN connection (IPsec ,PPTP , L2TP, OpenVPN,)

If not available 2FA in VPN yet, please add this feature in the near future. Into Omada system.
