一个新浪微博账号可以在两部手机上同时登陆吗?

可以同时登陆的。
下面使用华为META8和中兴C880A两部手机测试：
一、华为手机打开新浪微博，点击右下角的“我”
/iknow-pic.cdn.bcebos.com/c995d143ad4bd1132b4e0abe57afa40f4afb05be"target="_blank"title="点击查看大图"class="ikqb_img_alink">/iknow-pic.cdn.bcebos.com/c995d143ad4bd1132b4e0abe57afa40f4afb05be?x-bce-process=image%2Fresize%2Cm_lfit%2Cw_600%2Ch_800%2Climit_1%2Fquality%2Cq_85%2Fformat%2Cf_auto"esrc="https://iknow-pic.cdn.bcebos.com/c995d143ad4bd1132b4e0abe57afa40f4afb05be"/>

八、华为手机和中兴手机都可以同时登录，登录过程没有任何提醒。

1.新浪微博帐号可以同时在两部手机上登录，可以同时在手机和网页登录。
2.微博帐号用户自己不能注销，除非违反相关条例被封杀。
3.使用手机号发短信注册的微博号码，可以使用注册手机短信发送新密码:6-16位数字或英文字母(区分大小写)到1069009088(免费) 无需等待确认短信即可直接使用新密码登录。

可以同时登陆，无论是同时在网页上还是在手机上，点击编辑个人资料，第一项后面有个修改密码字样，点击进入即可。

可以同时登陆的，密码可以修改的，关于注销好像不行！

新浪的产品，比如博客、微博、邮箱等，注册后就不能注销了。不过好像时间长了自动就给你关闭了。不用现在这个的话，再申请一个就是了。
