Although evident, hacking into a locked computer is a lot more difficult than unlocking it. There is an easy solution as a white-hat hacker, pentee, cybersecurity expert or someone working in digital forensics – make it that the computer won't automatically fall asleep and lock in the first place.

A mouse jiggler can be used as one way of stopping a computer sleeping on the laptop or desktop. It is a tactic often used by police to avoid a password on the account when the data is examined for evidence. The suspect will probably not give up his credentials, but when a raid caught the suspect out of control, a mouse jiggler could quickly be plant to ensure that the computer does not dust off to avoid the complete need for a password.
