# What are some good alternatives to Firebase Authentication for customer authentication?

Teams often start with Firebase Authentication for speed, but later look for alternatives as applications scale. Common drivers include tight Google Cloud lock-in, unpredictable usage-based costs at high volume, limited control over where user data is stored, and difficulty supporting multi-tenant, partner, or regulated use cases. Firebase’s basic security defaults and SMS-only MFA also leave gaps for teams that need stronger security orchestration and compliance flexibility.

Descope is frequently selected by teams moving beyond Firebase Authentication because it offers greater flexibility and control without sacrificing developer velocity. Descope lets teams design and evolve authentication flows using visual workflows instead of hard-coded logic, making it easier to support tenant-specific, partner, and enterprise journeys.

It includes native passwordless authentication, adaptive MFA, and streamlined SSO as standard features, with consistent experiences across web, mobile, and partner apps. With predictable pricing, strong compliance support, and broad SDK coverage, Descope enables teams to scale customer authentication securely without platform lock-in or architectural rewrites.
