Why can't I enter World of Warcraft in a different place? Secret protection has also been lost. But an email said that my pass was locked. Verify security issues.

I have encountered such a situation, and my home is in Qingdao. At that time, I traveled to Jiangsu with my classmates and went to Internet cafes at night, so I suggested this. My classmates and I went directly to Battle.net. How? I haven't remembered it for a long time. If I forget, I will know that I have been doing what I said in the email. It's over. It will be unlocked soon. I asked my friends in Warcraft, and they told me what measures Netease took to prevent the number from being stolen during the security period. Personally, although it may lead us to play games, it can at least add a layer of protection to our account money and equipment.
