CRM PLUS on LINE vs OTP Login with Phonefor Shopify (2026)
CRM PLUS on LINE and OTP Login with Phone, while both boasting 5/5 ratings and falling under the 'Accounts and Login' Shopify category, address fundamentally different merchant needs. CRM PLUS on LINE focuses on leveraging the LINE messaging platform for customer engagement and marketing automation. It allows merchants to send targeted messages, automate abandoned checkout reminders, and create rich menus within LINE, specifically catering to businesses seeking to deepen customer relationships through this popular Asian messaging app. It also has a high barrier to entry, as LINE is used in the Asian market primarily. OTP Login with Phone, conversely, prioritizes streamlined and secure customer authentication. By replacing traditional passwords with one-time passwords sent via SMS or email, it offers a friction-free login experience. Its features, like customizable OTP settings and support for popular SMS providers, are geared towards merchants aiming to reduce cart abandonment and improve account security. The focus is less on ongoing engagement and more on the initial login and checkout phases. The key differentiator lies in their respective focuses: customer relationship management via messaging versus enhanced account security and simplified login.

Our Verdict
The choice between CRM PLUS on LINE and OTP Login with Phone hinges on the merchant's specific objectives. If your business heavily relies on LINE for customer communication, especially in regions where LINE is dominant, and you seek to automate personalized marketing messages, CRM PLUS on LINE is the clear winner. The integration with Shopify customer tags and Shopify Flow allows for highly targeted and automated LINE campaigns.
However, if your primary concern is to streamline the login process, reduce friction during checkout, and enhance account security, OTP Login with Phone is the more suitable option. Its focus on OTP-based authentication provides a fast, secure, and user-friendly experience. It's particularly valuable for merchants experiencing high cart abandonment rates related to complicated logins or security concerns. While both apps offer value, they cater to different areas of the customer journey and address distinct business needs.
