Let's learn something new.

1. Log in:

   • "Log in" (or "log in to") is a phrasal verb that describes the action of entering credentials to access a computer system, website, or application.
   • Example: "You need to log in to your account to access the settings." Here, "log in" is the action of entering credentials.
   • Example: "Please log in using your username and password." In this sentence, "log in" describes the action you need to perform.

2. Login:

   • "Login" is a noun that refers to the process or instance of logging in, or it can refer to the credentials used for logging in (username and password).
   • Example: "Your login was successful." Here, "login" refers to the event or process of logging in.
   • Example: "I forgot my login details." In this sentence, "login" refers to the credentials (username and password) used for accessing the system.

3. Log-in:

   • "Log-in" is an adjective (though less common than "login" as a noun) used to describe something related to the process of logging in.
   • Example: "Enter your log-in information here." Here, "log-in" is used adjectivally to describe the type of information required.
   • Example: "The log-in page is down for maintenance." In this sentence, "log-in" describes the page where users enter their credentials.
