Generate user token for member

[bjarnef]

Currently it seems IMemberManager expose e.g. GenerateEmailConfirmationTokenAsync(), but there are others e..g. GenerateUserTokenAsync().
https://learn.microsoft.com/en-us/dotnet/api/microsoft.aspnetcore.identity.usermanager-1.generateusertokenasync?view=aspnetcore-10.0

E.g. to generate a token for One-Time Password (OTP).

It seems UserManager<MemberIdentityUser> can be injected though and used something like this:

var token = userManager.GenerateUserTokenAsync(memberIdentity, TokenOptions.DefaultProvider, "OTP");

var verify = memberManager.VerifyUserTokenAsync(
    memberIdentity,
    TokenOptions.DefaultProvider,
    "OTP", token.Result);

or

var verify = userManager.VerifyUserTokenAsync(
    memberIdentity,
    TokenOptions.DefaultProvider,
    "OTP", token.Result);
