EAP-TTLS does not support enrollment
Authentication will fail unexpectedly when EAP-TTLS is enabled, either Okta Verify or Phone are specified as required enrollment policy, and the user is not enrolled in that factor.

The U2F Security and Windows Hello MFA factors are not compatible with RADIUS-enabled implementations.
For additional information about the RADIUS apps refer to Configuring RADIUS applications in Okta.

Passwordless authentication
RADIUS authentication uses passwords as the primary authentication mechanism. Traditional RADIUS authentication cannot be performed with passwordless users. RADIUS can use other factors for authentication when the application setting property Okta performs primary authentication is unchecked. See2FA Only (Passwordless Mode) in RADIUS applications in Okta for addition detail.
For more information on passwordless authentication see Set up passwordless sign-in experience.
