一、英语sign in和sign up区别是什么

其实sign in和Sign up的区别很明显，主要来说sign in是登录的意思，sign up是注册的意思，接下来我就详细解释一下吧，不清楚的小伙伴快来看一看。

再补充一个常见短语，退出=sign out

sign up的意思是注册报名，跟…签订合同。在合同中表示签署的意思，在网站中通常是注册账号的意思。

sign in的意思是签到；注册；登记；签收。In有一定的指向性，表示需要签名就可以进入这个网址。在网站中通常是登录账号的意思。

Sign in：只是证明我来了。sign in本意是签到。例如，你上班时需要指纹打卡签到，（指纹信息）表明是你来上班了。网站也一样，在网站登录（类似签到）时，也会输入你的用户名信息，，表明是你来了。

Sign up：达成一种长期的合作关系。本意是签约。例如，和某公司签约，一般会填写你的个人详细信息，然后你就会成为公司的一员。网站也一样，在网站注册（类似签约）时，一般也会填写关于你的个人信息（例如，性别，年龄，手机号等等），这样你就成为了网站的一名普通成员了。
