To implement multiple identity users in ASP.NET Core MVC (e.g., having separate authentication for different types of users like admin, customer, etc.), follow these steps:<\/p>\n\n\n\n

1. Create Multiple User Models<\/strong><\/h3>\n\n\n\n

You will need separate models for different types of users if they have distinct properties. For example:<\/p>\n\n\n\n

<\/circle><\/circle><\/circle><\/g><\/svg><\/span><\/path><\/path><\/svg><\/span>
public<\/span> <\/span>class<\/span> <\/span>AdminUser<\/span> <\/span>:<\/span> IdentityUser<\/span><\/span>\n{<\/span><\/span>\n    <\/span>public<\/span> <\/span>string<\/span> AdminSpecificProperty <\/span>{<\/span> <\/span>get;<\/span> <\/span>set;<\/span> <\/span>}<\/span><\/span>\n}<\/span><\/span>\n<\/span>\npublic<\/span> <\/span>class<\/span> <\/span>CustomerUser<\/span> <\/span>:<\/span> IdentityUser<\/span><\/span>\n{<\/span><\/span>\n    <\/span>public<\/span> <\/span>string<\/span> CustomerSpecificProperty <\/span>{<\/span> <\/span>get;<\/span> <\/span>set;<\/span> <\/span>}<\/span><\/span>\n}<\/span><\/span><\/code><\/pre><\/div>\n\n\n\n
2. Create Separate DbContexts for Each User Type<\/strong><\/h3>\n\n\n\n
You can create separate DbContext<\/code> classes to handle different user types.<\/p>\n\n\n\n
<\/circle><\/circle><\/circle><\/g><\/svg><\/span><\/path><\/path><\/svg><\/span>
public<\/span> <\/span>class<\/span> <\/span>AdminDbContext<\/span> <\/span>:<\/span> IdentityDbContext<\/span><<\/span>AdminUser<\/span>><\/span><\/span>\n{<\/span><\/span>\n    <\/span>public<\/span> <\/span>AdminDbContext<\/span>(<\/span>DbContextOptions<\/span><<\/span>AdminDbContext<\/span>><\/span> options<\/span>)<\/span> <\/span>:<\/span> <\/span>base<\/span>(<\/span>options<\/span>)<\/span> <\/span>{<\/span> <\/span>}<\/span><\/span>\n}<\/span><\/span>\n<\/span>\npublic<\/span> <\/span>class<\/span> <\/span>CustomerDbContext<\/span> <\/span>:<\/span> IdentityDbContext<\/span><<\/span>CustomerUser<\/span>><\/span><\/span>\n{<\/span><\/span>\n    <\/span>public<\/span> <\/span>CustomerDbContext<\/span>(<\/span>DbContextOptions<\/span><<\/span>CustomerDbContext<\/span>><\/span> options<\/span>)<\/span> <\/span>:<\/span> <\/span>base<\/span>(<\/span>options<\/span>)<\/span> <\/span>{<\/span> <\/span>}<\/span><\/span>\n}<\/span><\/span><\/code><\/pre><\/div>\n\n\n\n
3. Configure Identity for Each User Type in Program.cs<\/code> (or Startup.cs<\/code>)<\/strong><\/h3>\n\n\n\n
Register each DbContext<\/code> and configure the identity options:<\/p>\n\n\n\n
<\/circle><\/circle><\/circle><\/g><\/svg><\/span><\/path><\/path><\/svg><\/span>
builder<\/span>.<\/span>Services<\/span>.<\/span>AddDbContext<\/span><<\/span>AdminDbContext<\/span>>(<\/span>options <\/span>=><\/span><\/span>\n    <\/span>options<\/span>.<\/span>UseSqlServer<\/span>(<\/span>builder<\/span>.<\/span>Configuration<\/span>.<\/span>GetConnectionString<\/span>(<\/span>"<\/span>AdminConnection<\/span>"<\/span>)))<\/span>;<\/span><\/span>\n<\/span>\nbuilder<\/span>.<\/span>Services<\/span>.<\/span>AddDbContext<\/span><<\/span>CustomerDbContext<\/span>>(<\/span>options <\/span>=><\/span><\/span>\n    <\/span>options<\/span>.<\/span>UseSqlServer<\/span>(<\/span>builder<\/span>.<\/span>Configuration<\/span>.<\/span>GetConnectionString<\/span>(<\/span>"<\/span>CustomerConnection<\/span>"<\/span>)))<\/span>;<\/span><\/span>\n<\/span>\nbuilder<\/span>.<\/span>Services<\/span>.<\/span>AddIdentity<\/span><<\/span>AdminUser<\/span>,<\/span> IdentityRole<\/span>>()<\/span><\/span>\n    <\/span>.<\/span>AddEntityFrameworkStores<\/span><<\/span>AdminDbContext<\/span>>()<\/span>;<\/span><\/span>\n<\/span>\nbuilder<\/span>.<\/span>Services<\/span>.<\/span>AddIdentity<\/span><<\/span>CustomerUser<\/span>,<\/span> IdentityRole<\/span>>()<\/span><\/span>\n    <\/span>.<\/span>AddEntityFrameworkStores<\/span><<\/span>CustomerDbContext<\/span>>()<\/span>;<\/span><\/span>\n<\/span>\n\/\/ Authentication Schemes<\/span><\/span>\nbuilder<\/span>.<\/span>Services<\/span>.<\/span>AddAuthentication<\/span>()<\/span><\/span>\n    <\/span>.<\/span>AddCookie<\/span>(<\/span>"<\/span>AdminScheme<\/span>"<\/span>,<\/span> options <\/span>=><\/span><\/span>\n    <\/span>{<\/span><\/span>\n        <\/span>options<\/span>.<\/span>LoginPath<\/span> <\/span>=<\/span> <\/span>"<\/span>\/Admin\/Account\/Login<\/span>"<\/span>;<\/span><\/span>\n        <\/span>options<\/span>.<\/span>AccessDeniedPath<\/span> <\/span>=<\/span> <\/span>"<\/span>\/Admin\/Account\/AccessDenied<\/span>"<\/span>;<\/span><\/span>\n    <\/span>})<\/span><\/span>\n    <\/span>.<\/span>AddCookie<\/span>(<\/span>"<\/span>CustomerScheme<\/span>"<\/span>,<\/span> options <\/span>=><\/span><\/span>\n    <\/span>{<\/span><\/span>\n        <\/span>options<\/span>.<\/span>LoginPath<\/span> <\/span>=<\/span> <\/span>"<\/span>\/Customer\/Account\/Login<\/span>"<\/span>;<\/span><\/span>\n        <\/span>options<\/span>.<\/span>AccessDeniedPath<\/span> <\/span>=<\/span> <\/span>"<\/span>\/Customer\/Account\/AccessDenied<\/span>"<\/span>;<\/span><\/span>\n    <\/span>})<\/span>;<\/span><\/span><\/code><\/pre><\/div>\n\n\n\n
4. Use Authentication Schemes in Controllers<\/strong><\/h3>\n\n\n\n
For different types of users, apply authentication schemes in the corresponding controllers:<\/p>\n\n\n\n
<\/circle><\/circle><\/circle><\/g><\/svg><\/span><\/path><\/path><\/svg><\/span>
[<\/span>Authorize<\/span>(<\/span>AuthenticationSchemes <\/span>=<\/span> <\/span>"<\/span>AdminScheme<\/span>"<\/span>)]<\/span><\/span>\npublic<\/span> <\/span>class<\/span> <\/span>AdminController<\/span> <\/span>:<\/span> Controller<\/span><\/span>\n{<\/span><\/span>\n    <\/span>\/\/ Admin actions<\/span><\/span>\n}<\/span><\/span>\n<\/span>\n[<\/span>Authorize<\/span>(<\/span>AuthenticationSchemes <\/span>=<\/span> <\/span>"<\/span>CustomerScheme<\/span>"<\/span>)]<\/span><\/span>\npublic<\/span> <\/span>class<\/span> <\/span>CustomerController<\/span> <\/span>:<\/span> Controller<\/span><\/span>\n{<\/span><\/span>\n    <\/span>\/\/ Customer actions<\/span><\/span>\n}<\/span><\/span><\/code><\/pre><\/div>\n\n\n\n
5. Login and Logout for Different User Types<\/strong><\/h3>\n\n\n\n
In your login action, you can specify the authentication scheme:<\/p>\n\n\n\n
<\/circle><\/circle><\/circle><\/g><\/svg><\/span><\/path><\/path><\/svg><\/span>
public<\/span> <\/span>async<\/span> Task<\/span><<\/span>IActionResult<\/span>><\/span> <\/span>AdminLogin<\/span>(<\/span>string<\/span> returnUrl <\/span>=<\/span> <\/span>null<\/span>)<\/span><\/span>\n{<\/span><\/span>\n    <\/span>var<\/span> result <\/span>=<\/span> <\/span>await<\/span> <\/span>_signInManager<\/span>.<\/span>PasswordSignInAsync<\/span>(<\/span>userName<\/span>,<\/span> <\/span>password<\/span>,<\/span> <\/span>false<\/span>,<\/span> <\/span>false<\/span>)<\/span>;<\/span><\/span>\n    <\/span>if<\/span> <\/span>(<\/span>result<\/span>.<\/span>Succeeded<\/span>)<\/span><\/span>\n    <\/span>{<\/span><\/span>\n        <\/span>return<\/span> <\/span>RedirectToAction<\/span>(<\/span>"<\/span>Index<\/span>"<\/span>,<\/span> <\/span>"<\/span>Admin<\/span>"<\/span>)<\/span>;<\/span><\/span>\n    <\/span>}<\/span><\/span>\n    <\/span>return<\/span> <\/span>View<\/span>()<\/span>;<\/span><\/span>\n}<\/span><\/span>\n<\/span>\npublic<\/span> <\/span>async<\/span> Task<\/span><<\/span>IActionResult<\/span>><\/span> <\/span>CustomerLogin<\/span>(<\/span>string<\/span> returnUrl <\/span>=<\/span> <\/span>null<\/span>)<\/span><\/span>\n{<\/span><\/span>\n    <\/span>var<\/span> result <\/span>=<\/span> <\/span>await<\/span> <\/span>_signInManager<\/span>.<\/span>PasswordSignInAsync<\/span>(<\/span>userName<\/span>,<\/span> <\/span>password<\/span>,<\/span> <\/span>false<\/span>,<\/span> <\/span>false<\/span>)<\/span>;<\/span><\/span>\n    <\/span>if<\/span> <\/span>(<\/span>result<\/span>.<\/span>Succeeded<\/span>)<\/span><\/span>\n    <\/span>{<\/span><\/span>\n        <\/span>return<\/span> <\/span>RedirectToAction<\/span>(<\/span>"<\/span>Index<\/span>"<\/span>,<\/span> <\/span>"<\/span>Customer<\/span>"<\/span>)<\/span>;<\/span><\/span>\n    <\/span>}<\/span><\/span>\n    <\/span>return<\/span> <\/span>View<\/span>()<\/span>;<\/span><\/span>\n}<\/span><\/span><\/code><\/pre><\/div>\n","protected":false},"excerpt":{"rendered":"
