一.邮箱需要获得客户端授权码
如何使用客户端授权码?
1 )进入 设置—>邮箱设置—>客户端授权密码 设置页面
2 ) VIP邮箱客户端授权密码需配合邮箱登录短信验证使用。如果没有开启短信登录验证,可点击链接开启邮箱登录短信验证服务。
在 使用 客户端授权码之前,需先设置 邮箱登录 短信 验证 。 查看 如何使用 邮箱登录短信验证
3)开启邮箱短信验证之后,重新进入授权密码设置页面,可以看到开启授权密码服务选项 。
选择“开启”,即可开始设置授权密码。
开启授权密码服务之后,将无法使用邮箱密码在客户端登录。
4 ) 点击增加授权密码按钮
验证成功后,编辑授权码的名称,以及输入授权码密码,授权密码为自定义密码,建议您输入字母+数字的组合密码,提高密码安全强度。
设置成功后,选择您要开启的客户端协议。
5)点击确认后将在此页面显示已添加的授权密码列表,
点击“停用”授权密码将被删除,无法再通过此授权密码登录。
设置时间、启用日期分别为添加授权密码时间和首次通过验证的时间。
注意:每个用户最多同时设置20个授权密码。设置满20个授权密码后会出现如下提醒:
