It's like ticking a box saying you agree to a contract's terms and conditions. Online signatures make electronic documents valid by confirming your identity. You may use it to sign online documents the same way you'd use a physical signature. In easier terms: An online signature is your virtual handwritten signature. Federal ESIGN ACT, an online signature is defined as 'an electronic sound, symbol, or process, attached to or logically associated with a contract or other record and executed or adopted by a person with the intent to sign the record.'
