I'm confused on how exactly to verify a phone with Authy.

I have a C#/MVC view that accepts a country code and phone number and I call AuthyClient.RegisterUser and that works fine. I store the AuthyId that comes back.

I then call AuthyClient.SendSms with force=true. <--- does this send them a verification code?

My test user didn't even enter a code on my site and in Twilio, he's showing as verified. Is that because he opened up the Authy app after getting registered?

Are there multiple ways to verify a phone then?

Twilio developer evangelist here.

The API requests you are making here, starting with the call to AuthyClient.RegisterUser is actually the way that you perform two factor authentication with the Authy APIs.

To verify a phone with Authy you only need to make two API calls. The first sends a verification code and the second requires the user to input the code they received and then verifies it.

I can see you're using the authy.net library, which is sadly archived on GitHub now because it wasn't kept up to date. I'm not a .NET developer, but from what I can see in the codebase it didn't support the Verify endpoints. For this reason, I'd recommend you construct the HTTP requests yourself.

Take a read through the Verify documentation, it has all the URLs you need to make requests to including the required parameters. Let me know how you get on with that.
