Shoulder surfing
Updated: 08/02/2020 by Computer Hope
Also known as shouldering, shoulder surfing describes a person who looks over another person's shoulder as they enter data into a computer or another device.
Shoulder surfing could be used when you are entering your computer password, ATM (automated teller machine) pin, or credit card number. Criminals often use this technique to access personal accounts or read personal information, such as e-mails.
