ASP.NET Identity reset password

Question

How can I get the password of a user in the new ASP.NET Identity system? Or how can I reset without knowing the current one (user forgot password)?

Best way to Reset Password in Asp.Net Core Identity use for Web API.

Note* : Error() and Result() are created for internal use. You can return you want.

        [HttpPost]
        [Route("reset-password")]
        public async Task ResetPassword(ResetPasswordModel model)
        {
            if (!ModelState.IsValid)
                return BadRequest(ModelState);
            try
            {
                if (model is null)
                    return Error("No data found!");


                var user = await _userManager.FindByIdAsync(AppCommon.ToString(GetUserId()));
                if (user == null)
                    return Error("No user found!");

                Microsoft.AspNetCore.Identity.SignInResult checkOldPassword =
                    await _signInManager.PasswordSignInAsync(user.UserName, model.OldPassword, false, false);

                if (!checkOldPassword.Succeeded)
                    return Error("Old password does not matched.");

                string resetToken = await _userManager.GeneratePasswordResetTokenAsync(user);
                if (string.IsNullOrEmpty(resetToken))
                    return Error("Error while generating reset token.");

                var result = await _userManager.ResetPasswordAsync(user, resetToken, model.Password);

                if (result.Succeeded)
                    return Result();
                else
                    return Error();
            }
            catch (Exception ex)
            {
                return Error(ex);
            }
        }
