This research aims to analyze the published research on UTAUT2 (a unified theory of acceptance and use of technology) from 2012 to 2023, focusing on the research pattern and growth patterns. The research on UTAUT2 from 2012 is summarised using a bibliometric strategy and a systematic literature review analysis. There were 115 papers reviewed for their study designs, theoretical underpinnings, methodological approaches, authorship distribution, funding agencies, academic publications, and overall contributions to the corpus of UTAUT2 knowledge. The data was visualized using VOS viewer, and future study topics were proposed using the TCCM framework, an acronym for theory (T), context (C), characteristics (C), and methodology (M). Based on the results, interest in UTAUT2 is increasing as a topic of study. The top 15 mostcited publications were subjected to a systematic literature review, which examined the new models' parsimony. Also, the research includes a special part devoted to discussing the origins of UTAUT2 and the people who have been instrumental in its promotion. Title, abstract, and keyword searches in Scopus provided the data for this analysis. Papers from the Scopus database published in the UTAUT2 research field were used for this analysis. In the future, researchers may do a meta-analysis of the various bibliometric clusters. Practitioners may utilize the findings of this study to better plan for the future of technology acceptance, adoption, and use. To the authors' knowledge, this is one of the earliest studies to use the TCCM framework to analyze the patterns and growth trends within the UTAUT2 research literature to make predictions about the direction of future research
