What is Stytch?
Stytch builds authentication infrastructure: APIs and SDKs for passkeys, one-time passcodes, magic links, SSO/SCIM for B2B apps, and device-fingerprinting fraud detection. In October 2025, Twilio announced it had acquired Stytch to build what it calls "the intelligent identity layer for the internet"; Stytch continues to operate its own APIs and dashboard.

Key capabilities
- Authentication methods: Passkeys, SMS/email OTP, magic links, OAuth and biometrics via prebuilt SDKs.
- B2B features: Multi-tenant organizations, SSO (SAML/OIDC) and SCIM provisioning.
- Fraud tooling: Device fingerprinting and risk signals to flag suspicious sign-ups or logins.
Evaluate MAU-based pricing against your growth curve, confirm SSO/SCIM connection limits on lower tiers, and check compliance needs (HIPAA/BAA is an Enterprise add-on) before migrating production login flows.
Shortlist Stytch for passwordless or B2B authentication where you want dedicated auth APIs rather than building login flows in-house. Confirm how the Twilio acquisition affects your roadmap and support relationship before committing long-term.
Stytch remains a strong option for teams that want auth handled outside their core codebase, but the October 2025 Twilio acquisition is a material change worth tracking for long-term roadmap and pricing stability.
