Authentication & Authorization · head-to-head
MojoAuth vs Stytch
MojoAuth is a passwordless authentication API offering OTP over SMS/email, magic links, passkeys/WebAuthn, and social login, plus SSO connections (OIDC/SAML) for enterprise buyers. Every request to its api.mojoauth.com backend requires an X-API-Key header, returning structured JSON errors ("API Key Required" / "Invalid API Key") when the key is missing or wrong. Pricing is free up to 25,000 monthly active users, with paid Startup and Enterprise plans beyond that.
Stytch provides passwordless authentication primitives — email magic links, SMS/WhatsApp OTP, passkeys, and OAuth social login — plus session and user management for consumer and B2B apps. API calls are authenticated with HTTP Basic Auth using a project's project_id as the username and its secret as the password against api.stytch.com, separate from the OAuth2 client-credentials scheme used only by its M2M Connected Apps endpoints. Stytch offers a free tier for early-stage usage alongside usage-based paid plans.
