我们在 Nodemailer 中使用我们的 Gmail 凭据来发送开发中的测试电子邮件。我们今天尝试发送一个与昨天相同的配置，但收到以下错误：

我做了一些研究，发现我应该打开 "Less secure apps" 但我找不到设置。

当我访问 https://myaccount.google.com/lesssecureapps 时，我得到 "Settings could not be read"

Answer 1

如果您是 Gsuite 管理员，则需要将其迁移到 oAuth。我不知道 google 是否暂时或永久禁用了 LSA。

https://gsuiteupdates.googleblog.com/2019/12/less-secure-apps-oauth-google-username-password-incorrect.html

LSA 已返回安全设置，我猜它已关闭一段时间。

Answer 2

这是 Google 方面的暂时性问题。到 11:44 UTC 时，我们回来了。 https://twitter.com/gsuite/status/1257266044957319169?s=20

Answer 3

我们设法使用应用密码快速修复了它。对于使用 Less Secure Apps 登录的任何人来说，这是一个微不足道的修复。您只需要设置 2FA（如果您还没有）并使用生成的应用程序密码从您的应用程序登录，而不是标准密码。

这比迁移到 OAuth 更容易，对于任何急于在生产中解决此问题的人来说，OAuth 通常是唯一的选择。
