A Nigerian fintech user has shared how OPay’s NightGuard feature prevented him from losing his entire savings to fraudsters. The customer, who recounted his experience, explained that cybercriminals attempted to drain his account during late-night hours, but the security measure stopped the unauthorized transactions.
NightGuard, a recently introduced feature by OPay, is designed to protect users from fraudulent activities by restricting large transactions during high-risk hours unless explicitly authorized. According to the user, he received multiple alerts of attempted withdrawals while he was asleep, but thanks to the system’s automatic security block, the transactions did not go through.

With increasing cases of online fraud in Nigeria, fintech platforms have been under pressure to strengthen their security frameworks. OPay’s NightGuard has been praised for adding an extra layer of protection, particularly during vulnerable periods when users may not be actively monitoring their accounts.
Cybersecurity experts have highlighted the importance of such proactive security features, urging financial institutions to adopt more real-time monitoring and fraud detection systems. Many users have also called for greater awareness on how to secure digital transactions, emphasizing the need for strong passwords, two-factor authentication, and vigilance against phishing scams.
OPay has reiterated its commitment to user safety, encouraging customers to activate NightGuard and explore other security settings available on the app. As digital banking continues to grow in Nigeria, the need for enhanced protection against cyber threats remains a top priority for fintech companies and regulators alike.
