foreign "Other" user group

[EJMustard]

Hello,

My mac login screen has a user called "other". THe icon is a silhouette of 3 heads. When I select "Other" two fields appear, one for name and one for password. I can access any of the user accounts on my computer by typing in the name and password for any them into these fields. What the heck is this account, how did it get there and how do I get rid of it

Its possible the root user was enabled.

regardless, its harmless and wont have an affect on OS X. but you can verify if Root user is enabled by going to System Preferences, Users & Groups, Login Options, click Join next to network server and from the Edit menu it will say enable or disable root.

"Other" is not a user - it literally means an other user than one that is listed. Check your Login Options in the Users & Groups system prefs.
