I am trying to share cookies among applications so that I don't have to constantly login on one app and login again in another.

This is the startup that I have on both applications

services.AddDbContext<DbContext>(options => options.UseSqlServer(Configuration["DatabaseConfiguration:ConnectionString"]));
services.AddMvc().AddJsonOptions(options =>

 options.SerializerSettings.ContractResolver
 = new Newtonsoft.Json.Serialization.DefaultContractResolver();
);
services.AddIdentity<ApplicationUsers, Roles>()
 .AddEntityFrameworkStores<DbContext>()
 .AddDefaultTokenProviders();
services.AddScoped<LogsData>();
services.AddScoped<ApplicationUsersData>();
services.AddScoped<CustomClaimsCookieSignInHelper<ApplicationUsers>>();

services.Configure<IdentityOptions>(options =>

 options.Password.RequireDigit = false;
 options.Password.RequireLowercase = false;
 options.Password.RequireNonAlphanumeric = true;
 options.Password.RequireUppercase = true;
 options.Password.RequiredLength = 6;
 options.User.AllowedUserNameCharacters =
 "abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789-._@+";
 options.User.RequireUniqueEmail = false;
 options.SignIn.RequireConfirmedEmail = false;
 options.SignIn.RequireConfirmedPhoneNumber = false;
);

services.Configure<CookiePolicyOptions>(options =>

 // This lambda determines whether user consent for non-essential cookies is needed for a given request.
 options.CheckConsentNeeded = context => false;
 options.MinimumSameSitePolicy = SameSiteMode.None;
);
services.AddDataProtection()
 .PersistKeysToFileSystem(KeyRingConfigurationManager.GetBasePath())
 .SetApplicationName("AppName");

services.ConfigureApplicationCookie(options => 
 options.Cookie.Name = ".AppName.Shared";
);

services.ConfigureApplicationCookie(options =>

 // Cookie settings
 options.Cookie.HttpOnly = true;
 options.ExpireTimeSpan = TimeSpan.FromMinutes(5);

 options.LoginPath = "/Identity/Account/Login";
 options.AccessDeniedPath = "/Account/AccessDenied";
 options.SlidingExpiration = true;
);
services.AddMvc().SetCompatibilityVersion(CompatibilityVersion.Version_2_1);

When I run my application, I noticed that in my Key folder, a key xml file appears. However, when I start the second application and navigate to my controller that is authorized, I get kicked back to the login page meaning I wasn't logged in. What else am I missing?

can you please check about adding session with your services? I have tried some code regarding that and it does working fine for me.

 services.AddSession(options =>
 
 // Set a short timeout for easy testing.
 options.IdleTimeout = TimeSpan.FromDays(2);
 options.Cookie.HttpOnly = true;
 options.Cookie.Name = CookieAuthenticationDefaults.AuthenticationScheme;
 );

Also add usesession() in your COnfigure() method.

 app.UseSession();
