python错误登录，甚至从gmail启用imap

Question

我试图在python中使用imap，但每次都会出错，我按照所有步骤从gmail激活imap并解锁captcha，但在第一次运行后，我收到了此错误，请立即提供帮助，谢谢

raise self.error(dat[-1])
imaplib.error: b'[AUTHENTICATIONFAILED] Invalid credentials (Failure)'

gmail发布后，我收到了来自gmail的Alert security，来自imap的所有访问都被阻止

使用的代码是`

import imaplib, email 

    user = 'USER_EMAIL_ADDRESS'
    password = 'USER_PASSWORD'
    imap_url = 'imap.gmail.com'

如果您是在云主机或类似设备上运行此功能，那么如果不实现OAuth身份验证（或者特定于应用程序的密码），此功能可能永远无法工作

谷歌的帐户安全设置似乎只允许可能的最终用户主机登录。如果您在您的个人计算机上运行它（您也从该计算机登录），则必须激活简化的安全设置、生成特定于应用程序的密码或实现OAuth
