This study explored the effect of performance expectancy (PE), effort expec-tancy (EE), social influence (SI), lifestyle compatibility (LC), and perceived trust (PT) on intention to adopt mobile banking (IMB), as well as the effect of facilitating conditions (FC) and intention on the adoption of mobile banking (AMB) among Bangladeshi millennials. Additionally, this study investigated the moderating effect of age, gender, and education level of Bangladeshi millennials under the premises of the unified theory of ac-ceptance and use of technology (UTAUT) model. Upon adopting the cross-sectional research design, quantitative data were gathered from 312 Bangla-deshi millennials via online survey. The study outcomes revealed that SI, LC, and PT displayed significantly positive effect on IMB, as well as for the effect of FC and intention on AMB. Additionally, IMB appeared to mediate the linkages of SI, LC, and PT with AMB. The findings revealed that age moderated the relationship between SI and IMB. In promoting green finan-cial services and fostering economic growth through mass AMB practices in Bangladesh, the government and its financial service providers should high-light on the benefits of using MB practices, as well as information security related details, to build trust among Bangladeshi millennials.
