Hi Van and welcome to Our :-)

We have different services that you can use as you can see here

https://our.umbraco.org/documentation/Reference/Management/Services/

I know that this service is not on the list yet, but we also have a UserService which you can use for Umbraco backoffice users.

Hope this helps,

/Dennis

I have tried this but no joy...

var result = await signInManager.PasswordSignInAsync(user.UserName, loginModel.Password, isPersistent: true, shouldLockout: false); 

this returns true however when i redirect the page to HttpContext.Current.Response.Redirect("http://localhost:57933/umbraco/#");

i still get umbraco standard login box.

any help is much appreciated!!! thanks

To log in a backoffice user use the PerformLogin method:

//Login backoffice user.
//NOTE: PerformLogin method not documented in official doc. Src: https://github.com/umbraco/Umbraco-CMS/blob/dev-v7/src/Umbraco.Web/Security/WebSecurity.cs#L150
var sessionTimeoutInSeconds = UmbracoContext.Security.PerformLogin(userId);

Hope this help.
