Our Verdict
For Shopify merchants primarily focused on securing and streamlining login on their *individual* store with a straightforward OTP solution, **OTP Login with Phone** is the better choice.

Despite the lack of reviews, its features point towards addressing the needs of larger, more complex business operations.
