[ValidateAntiForgeryToken]
public async Task<IActionResult> Login(LoginViewModel model, string returnUrl = null)

{
var result = await _signInManager.PasswordSignInAsync(model.Email, model.Password, model.RememberMe, lockoutOnFailure: false);
if (result.Succeeded)
{
_logger.LogInformation("User logged in.");
return RedirectToLocal(returnUrl);
}
if (result.RequiresTwoFactor)
{
return RedirectToAction(nameof(LoginWith2fa), new { returnUrl, model.RememberMe });
}
if (result.IsLockedOut)
{
_logger.LogWarning("User account locked out.");
return RedirectToAction(nameof(Lockout));
}

return View(model);
}
}
return View(model);

电子邮件：[e-mail]

看看UserManager.GeneratePasswordResetTokenAsync和UserManager.ResetPasswordAsync。

如果你正在处理的场景是"忘记密码"，那么你很可能想向用户发送一封带有链接的电子邮件。此链接将用户带到一个操作，该操作将重置令牌作为查询参数。然后，用户可以单击此链接重置密码，并从此处进行ResetPasswordAsync调用。

如果这是你正在看的场景(你的帖子没有具体说明(，那么你应该看看这里的微软指南：启用帐户确认和密码恢复

一些精简代码(仅用于说明/教学目的(：

// Get the user by email - may need to be careful of casing here
IdentityUser user = _userManager.Users.First(x => x.Email == "[e-mail]");
// Generate the reset token (this would generally be sent out as a query parameter as part of a 'reset' link in an email)
string resetToken = await _userManager.GeneratePasswordResetTokenAsync(user);
// Use the reset token to verify the provenance of the reset request and reset the password.
IdentityResult updateResult = await _userManager.ResetPasswordAsync(user, resetToken, newPassword);
