Shopify has a one-time code sign-in, and it is not this one. The newer customer accounts are passwordless: the shopper enters an email address and receives a six-digit verification code, no password required. The word phone does not appear in that flow. So a store whose customers think of their phone number as their identity, which is most of India and much of the Gulf, has a gap the platform does not fill.

It is a deeper gap than it looks, and worth understanding before comparing features. Shopify's session is keyed to email: an outside identity provider has to plug in through OIDC, that is limited to the top plan, and even then Shopify identifies the customer from the email and subject claims in the token. There is no phone claim. So no app on this page can make a phone number the login itself. What they do instead is intercept earlier, verify the number by text, and attach it to a customer record, where the phone field is unique and in international format, so the same number cannot belong to two customers.

What to look for in a Phone Number app

Whose messages, and what they cost: Every app here brings its own SMS pipeline, and the provider is named on the listing. That decides delivery rates in your country and who you chase when codes stop arriving on one carrier. Ask whether you bring your own account or buy credits from the vendor.
What the customer record ends up looking like: Since the phone number is unique on a customer, ask what happens when a family shares one, when somebody changes numbers, and whether an existing email-based account gets merged with the phone-verified one or quietly duplicated.
Where the prompt appears: Login, registration, cart and checkout are different moments with different costs. A verification step before checkout doubles as fraud screening for cash-on-delivery orders, which is why several of these bundle it, and it also adds friction to every order you were going to get anyway.
The fallback when the code never comes: Texts fail. A second channel, email or a messaging app, and a support path for somebody locked out of their own account, is what separates a login you can run from one that generates tickets.

Built for Shopify
Built for Shopify is the highest level of recognition Shopify awards an app. To earn the badge, an app must meet Shopify's standards for safety, performance, ease of use, and proven usefulness: it cannot slow down the admin, storefront, or checkout, must integrate seamlessly into the Shopify admin, and must demonstrate quality through installs, reviews, and ratings over time.
