Which word is correct Log in or Login?

For an employee's daily log, to fill it's in and out timing. What word is preferable in that context?

"Login in" and "login" are just like "back up" and "backup", and many other similar expressions.

The double word form is a verb, while the single word form is a noun.

Try parsing the verb or pluralizing the noun. There's only one way it sounds right:

  • "He logs in every day", not "He logins every day".
  • "There were several logins yesterday", not "There were several logs in yesterday".


  • "He backs up the data", not "He backups the data".
  • "The backups are stored elsewhere", not "The backs up are stored elsewhere".

In your example, you could say "The employee logs in upon arrival and logs out upon leaving" and "The logins and logouts of all the employees are recorded in this book".

    You should use "login" where you need a noun, and "log in" where you need a verb. Nov 21, 2019 at 14:40

    @Swapnil You could use "-ing" form (of the verb) to think of it. "Logging in..." and absolutely not "Loginning" :) Nov 21, 2019 at 14:43
  • Thanks a lot for both of your time and efforts.
