Hi @David Thielen , I deduce you are using the default identity code generated by the blazor app template, so that you might also find the DeletePersonalData.razor in Components ->Account -> Pages -> Manage folder. Then I trust you will find that the default delete user action would only delete user account by await UserManager.DeleteAsync(user);
To delete the rows in the dbo.AspNetUserClaims table, we might manually add code below.
var claims = await UserManager.GetClaimsAsync(user);
var res = await UserManager.RemoveClaimsAsync(user, claims);
I had a test in my side which worked well for me.
