Log in 表示进入一个系统、账户、网站或应用。Sign in 意思相同，很多网站的按钮就写这个表达。连写的 login 是名词，可以指登录信息或登录行为，例如 login details、login page。

log in / sign in (to + account/website); log in with + email/password; login (noun): login details, login page
- I can't log in to my work email because I forgot my new password.
- Log in with your student account to see your exam results.
- Keep your login details somewhere safe and never share them with anyone.
修改原因
修改前I tried to login to the website three times, but it didn't work.
修改后I tried to log in to the website three times, but it didn't work.
动词分成两个词：log in、logged in、logging in。Login 连写用于名词，或放在另一个名词前修饰它，例如 your login、the login screen。Tried to 后面需要动词，所以写 log in。
不要混淆 sign in 和 sign up。Sign up 是注册、创建账户：I signed up last week。Sign in 和 log in 是进入已经拥有的账户。如果指输入的用户名，username 更明确；login details 通常把用户名和密码合在一起说。
动手练习
I already have an account, so I just need to ___ with my email and password.
查看答案
log in — 账户已经存在，现在只需进入它，所以选 log in。Sign up 表示新建账户，题目中并不需要再注册。
描述一次登录邮箱、银行或学习平台遇到的问题。说明哪里出错，以及怎样解决。
