Yes you can integrate with any provider. the pipeline [0] is the enforcement part – performing MFA checks like "Is MFA enabled on user? is it applicable for this request (can be turned off for programmatic api-based access, for example) etc."

It's the job of the application to prompt caller for 2FA input and verify it using the provider/device of your choice.

But to save you time even with that implementation, ASPSecurityKit has a category of products called source packages, which provide full implementation of several commonly needed functionality, including 2FA workflow [1], installed right into your project as source code, so you can switch to any MFA provider easily by modifying the code that sends MFA token to the device.
