Log in is always a great word to know.
So is slumgullion. Does it mean:
a stew of meat, vegetables, potatoes, etc.
a children's mummer's parade, as on the Fourth of July, with prizes for the best costumes.

Many who are neither professionals in the computer field nor amateur tech enthusiasts decry the use of the solid form login as a verb, and with reason. It doesn’t behave like a normal verb. You cannot say you have loginned, and you are never in the process of loginning. EXPANDMoreover, you cannot even ask someone to login you; you must ask that person to log you in. Clearly, it is the two-word phrase log in that functions fully as an English verb and not the solid form. Normally, we would expect log in, the verb phrase and login, the noun to behave in the same way as similar pairs: blow out/blowout, crack down/crackdown, hang up/hangup, splash down/splashdown, turn off/turnoff, where the two-word phrase is a verb and the one-word form a noun. LINEBREAKAnd yet, this gluing together, this solidification and use of terms like login, logon, backup, and setup as verbs is so common in the computer universe that that world’s inhabitants take it for granted. Not everyone, however. Some well-known software companies, for example, carefully maintain the distinction in their programs and documentation. LINEBREAKBut habits are difficult to change. Those who react to the one-word verb as an error will probably have to get used to it, and those who use the one-word verb will have to recognize that others will see it and wince

log
"to enter into a log book," 1823, from logbook "daily record of a ship's speed, progress, etc." (1679), which is so called because wooden floats were used to measure a ship's speed. To log in in the computing sense is attested from 1963.

log in definition

security
(Or "login", "log on", "logon") To start a session with a system, usually by giving a user name and password as a means of user authentication. The term is also used to mean the ability to access a service (also called an account), e.g. "Have you been given a login yet?"
"Log in/on" is occasionally misused to refer to starting a session where no authorisation is involved, or to access where there is no session involved. E.g. "Log on to our Web site!"
"login" is also the Unix program which reads and verifies a user's user name and password and starts an interactive session.
The noun forms are usually written as a single word whereas the verb forms are often written as two words.
To end a session is to "log out" or "off".

Idioms & Phrases

log in

Also, log on. Enter into a computer the information needed to begin a session, as in I logged in at two o'clock, or There's no record of your logging on today. These expressions refer especially to large systems shared by numerous individuals, who need to enter a username or password before executing a program. The antonyms are log off and log out, meaning "to end a computer session." All these expressions derive from the use of log in the nautical sense of entering information about a ship in a journal called a log book. [c. 1960]
