Humanmark vs OTP Login with Phonefor Shopify (2026)
Humanmark and OTP Login with Phone both aim to enhance security for Shopify stores, but they address fundamentally different challenges. Humanmark focuses on preventing bot purchases by implementing hardware-backed, biometric verification at checkout for specifically tagged products. It appeals to merchants battling scalpers and automated buying programs seeking to secure limited edition or high-demand items. A core strength of Humanmark is its emphasis on completely avoiding customer data collection during verification. OTP Login with Phone, in contrast, prioritizes streamlined and secure customer login and registration by replacing traditional passwords with one-time passwords (OTPs) sent via SMS or email. It offers a smoother customer experience by enabling faster account creation and login, thus potentially boosting conversions. The target audience for OTP Login with Phone includes a broad range of Shopify merchants aiming to improve account security and user convenience. The key difference lies in the problem being solved: Humanmark prevents bots, while OTP Login with Phone secures and simplifies the login process for legitimate customers.

Our Verdict
The choice between Humanmark and OTP Login with Phone depends entirely on a merchant's specific security needs. If the primary concern is preventing bots from purchasing limited-edition or high-demand items, then Humanmark, despite its lack of reviews, is the more targeted solution. Its hardware-backed verification offers a robust defense against sophisticated bots. However, merchants who simply want to enhance the security and convenience of customer logins and registrations should opt for OTP Login with Phone. Its perfect rating and numerous positive reviews indicate a reliable and well-received app for improving user experience and reducing password-related security risks.
Given the current data available in 2026, it would be prudent to proceed with caution with Humanmark due to the lack of reviews and proof of concept from other merchants. More information would be needed before recommending it in the absence of user feedback.
