The data shows that 71 percent of Vietnamese respondents use smartphones as their primary internet connection tool. Notably, 57 percent of users store identity documents, such as passports and citizen ID cards, on their devices—a figure higher than the regional average of 49 percent. Other stored data includes login passwords, work emails, and bank account information. In response to these vulnerabilities, the Vietnam Banks Association and BAC A BANK have issued warnings regarding high-tech crimes. Financial institutions are advising users to delete photos of citizen identity cards, passports, and credit cards from their mobile devices to prevent identity theft and unauthorized online loans. Security recommendations also include exercising caution with suspicious links or QR codes and never sharing OTP codes or passwords with others. ## Timeline ### 2026-09-05: Banks warn against storing sensitive ID photos on mobile devices Vietnamese banks warn against storing photos of ID cards, passports, and bank cards on mobile devices to prevent hackers from committing identity theft and financial fraud. 3 sources. https://clstr.news/cluster/banks-warn-against-storing-sensitive-id-photos-on-mobile-devices ### 2026-09-05: Vietnam smartphone users store high levels of sensitive personal data A Kaspersky survey shows Vietnamese smartphone users store high levels of sensitive data, including ID documents and bank info, acting as ‘digital safes’ despite lagging security habits. 3 sources. https://clstr.news/cluster/vietnam-smartphone-users-store-high-levels-of-sensitive-personal-data --- Cite as: Smartphone data privacy concerns in Vietnam.
