This study investigated the level of awareness of personal data protection among Facebook** and Instagram** users. The research evaluated the number of Facebook and Instagram users who have taken precautions to secure their personal data, why they did so, and the identification of regulatory authorities responsible for data protection in Nigeria. The Privacy Calculus Theory was used as the theoretical framework. The survey research design was used for this study, with the web-based questionnaire as the instrument for data collection. A sample size of 396 was drawn from the student population at the University of Port Harcourt. The data were analyzed in tables using frequency and percentage. The results indicated that users are strongly aware of the significance of safeguarding personal data on Facebook and Instagram. The users acknowledged implementing precautionary steps to safeguard their personal data. However, they still need to determine the specific agencies and regulatory entities accountable for ensuring the safety of personal data. In order to tackle this problem, the study recommended that the University management and student bodies should organize specific educational workshops to promote understanding of the pertinence of safeguarding personal data on social media platforms (Solove, 2021), create easily accessible materials and guidelines on the University of Port Harcourt portal designed for social media users, outlining the best methods for protecting personal data, including personal data protection awareness in its orientation programs and student events and also set up a system for reporting potential data breaches and offer assistance to affected users. ** – A social network owned by “Meta”, which is recognized as extremist in Russia
