Smartphones are the world's most widely used personal computing devices. PINs and passcodes have long been the most popular methods of authentication in smartphones, and even in the pre-smartphone era. Due to the inconvenient nature of PINs and passcodes, a new biometric authentication method for smartphones was developed and has been gaining traction in terms of adoption, beginning with flagship devices, and progressing to some mid-range devices. The purpose of this article is to investigate the factors that influence smartphone owners' acceptance of biometric authentication methods by developing a new model based on the Technology Acceptance Model (TAM) and validating it against survey data collected from 233 Indonesian smartphone owners via an online survey and analyzed using Structural Equation Modeling (SEM). The findings indicate that the majority of Indonesian smartphone owners have a favorable attitude toward biometric authentication, which is the primary reason for their willingness to adopt it. Additionally, it is discovered that the perceived usefulness of a biometric authentication method on a smartphone outweighs its perceived ease of use, and that the internal user motivation of perceived enjoyment has a greater impact on biometric authentication adoption on a smartphone than both the external user motivation of social influence and the intrinsic value of perceived security of a biometric authentication method.
