PingID allows you to sign on to all your applications with the added security of multi-factor authentication (MFA). Email authentication enables you to receive a one-time passcode (OTP) by email, and use it for PingID authentication.
It is not possible pair your email address to PingID using the VPN interface. However, if you have already paired your email address to receive an OTP for PingID authentication when accessing other resources, you can also use it for PingID authentication when accessing your VPN.
If you have not paired your email address for authentication with other resources and your organization allows you to manage your devices, set up email authentication through the PingID My Devices management page. For more information, see Adding a device.
