An inaccurate accreditation of voter causes problems in the electoral process by raising doubts about the election’s inclusiveness and outcome and by opening up avenues for fraud, manipulation and sometimes violence. The use of the bimodal voter accreditation system (BVAS) seems to be a game changer. This study investigates the impact of BVAS on the credibility of elections in the 2023 Adamawa state gubernatorial election in central senatorial district using primary data sourced from questionnaires. In preparing this work Innovation Diffusion Theory (IDT) was adopted as theoretical framework. The major objective of this study is to examine the effect of the Bimodal Voter Accreditation System (BVAS) on credibility of elections in Nigeria with the 2023 Adamawa State Gubernatorial election in central senatorial district as scenario. The findings revealed that voters are very much aware of the use of BVAS in the 2023 gubernatorial elections and it is statically significant at 5% level of 0.05. The study also revealed that there is no adequate voter education and orientation about the deployment of the (BVAS). Furthermore, there is a significant impact of bimodal voter accreditation system (BVAS) on the credibility of the 2023 Adamawa State Gubernatorial election. it was also examined that there is low level of dysfunction of the bimodal voter accreditation system (BVAS) in the 2023 Adamawa State Gubernatorial election in central senatorial district. The study recommends among others that voters awareness should be continuous even after elections. This will enable electorates to prepare for elections beforehand. It will also reduce the delays associated with voting patterns. It is evident that there is improvement in the performance of the BVAS but frequent update and upgrade of the BVAS is required to maintain its efficiency and effectiveness for future elections. Finally, this work may be a contribution to other available literature but can act as catalyst for further extensive research on BVAS.
