This isn't touched on in the two factor documentation, how do we go about generating the recovery codes?

In dotnet identity we should be able to do the following:

private readonly UserManager<MemberIdentityUser> _userManager;

var codes = await _userManager.GenerateNewTwoFactorRecoveryCodesAsync(member, 6);
TempData["RecoveryCodes"] = codes;

This would allow them to be shown one time on the confirmation page.

However for the life of me, I cannot figure out how to get Umbraco to do this with members.
