Electronic signature 

Most frequently referred to as the legally binding, electronic equivalent of an individual’s handwritten signature, which can be as basic as a typed name, a credential such as a password, or a digitized image of the handwritten signature. A deprecated term with currently no consensus on its meaning, often used as a synonym for “digital signature”. (Source: heise.de; Am J Transl Res. 2016; 8(3): 1560–1580)
