推荐答案

这是一个安全问题，默认情况下，Gmail阻止自定义应用程序访问您的电子邮件帐户.您可以将其设置为接受来自应用程序的登录.

Its a security issue, Gmail by default prevents access for your e-mail account from custom applications. You can set it up to accept the login from your application.

您需要通过以下链接转到安全设置: https://www.google. com/settings/security/lesssecureapps 并启用安全性较低的应用.这样您就可以从所有应用程序登录.

You need to go to security settings at the followig link https://www.google.com/settings/security/lesssecureapps and enable less secure apps. So that you will be able to login from all apps.
