MojoAuth vs Sinch Verification API

MojoAuth gives consumer apps a single API for passwordless customer authentication across web and mobile. Sign-in options include passkeys, magic links, email and phone one-time passwords, social login, and Google One Tap Login. Teams can keep password login available while users move to passwordless access. Developers get REST APIs, SDKs in 22+ languages, and webhooks for real-time events. Listed integrations include Google, Apple, Facebook, Microsoft, Okta, Salesforce, Shopify, and WordPress. The Free plan is free for up to 25,000 MAUs, with unlimited total users, email OTP, magic links, Google and Facebook login, and basic attack protection. Business Pro is $120 a month, billed monthly, at the displayed price for 25,000 MAUs; the pricing note separately lists paid access from $50/mo. A 30-day trial is available. Business Pro charges $0.06 per MAU above the selected tier. Enterprise (Private Cloud) is contact-sales priced and includes no MAU cap, up to 15,000 requests per second, and a dedicated private cloud. Enterprise support includes 24/7 assistance.

Sinch Verification API provides multi-factor authentication and phone-number verification for app sign-up, login, and password resets. Developers can use one-time passwords, password-free verification, or other account checks through backend REST APIs and native Android and iOS SDKs. Verification methods include SMS, voice calls, flash calls, and data verification. Sinch describes multilingual service across devices and platforms, with fallback options for delivery, conversion, and price, supported by more than 600 direct tier-1 operator connections. Its Dashboard shows verification results and delivery and conversion metrics in real time. Named identity integrations include Okta and Auth0, while developer guides also cover ForgeRock and SAP. Data Verification requires mobile data to be enabled, and Sinch advises contacting an account manager to use it. For SDK requests from untrusted mobile devices, Sinch recommends Public Authentication and says verification callbacks should validate requests to help prevent fraud. The service has free access and trial credit through Sinch Build. Pay-as-you-go verification is billed per request; SMS pricing varies by country and operator, while flash calls have a fixed price per attempt.
