I dropped and damaged my laptop and am now looking to have it repaired by an Apple approved service engineer. However, I am a little concerned about security with regards to my banking information etc. and wonder if creating a second user facility would allow my laptop to be accessed without my passwords and other information being vulnerable. I can still use the machine so creating a second user would not be a problem. Just concerned that I may have overlooked something, not having had to do this in the past. Thanks in advance.
