Talk:log in - Wiktionary

https://en.wiktionary.org/wiki/Talk:log_in

> The etymology is false. "log in" is a corruption of "log on" - possibly a conflation of "log on" and "clock/sign in".

> "Log on" was (and still is) a command in some systems indicating that a connection session to a mainframe was being started. Literally it means "start logging" - start keeping a record of actions taken.
