Owing to all that screwing around, I got this sent to me:
亲爱的用户:
你正在尝试使用第三方客户端(如Foxmail邮件客户端)登录QQ邮箱,由于密码错误,系统暂时阻止你登录。若你开启了独立密码,请使用独立密码登录。若未开启,请开启后使用独立密码登录。
如果这并非你本人所为,建议你登录QQ安全中心修改帐号密码。你也可以下载更安全快捷的QQ邮箱客户端,全面支持邮件通用协议,为大部分邮箱提供自动配置功能,免却客户端添加帐号的繁琐步骤。立即体验
Which I believe means:
Dear User:
You are trying to use a third party client (such as Foxmail mail client) login QQ mailbox, because the password is wrong, the system temporarily prevent you from logging in. If you have an independent password, please log in using a separate password. If it is not turned on, please use a separate password to log in.
If this is not your own, I suggest you log QQ security center to modify the account password. You can also download a more secure and fast QQ mailbox client, fully support the mail general agreement, for most of the mailbox to provide automatic configuration function, eliminating the cumbersome steps to add the account client. Experience immediately
So I'm wondering what the hell is this "independent password" thing. I went to the web QQ, went to Settings > Accounts > Independent Password Setting
Got told:
Your QQ ID has not been applied to one of protection method such as Mobile for password protection or QQ MobileToken or QQ Token. To protect your interests, temporarily unable to turn on Independent Password for you.
And there's a button there called "Bind now", but that sends me to the same QQ Security Center (aq.qq.com)
So, like, they really, really, really want me to use SMS verification or some such security measure first?
