Authalla - 2026 Pricing, Features, Reviews & Alternatives

Authalla is a multi-tenant OAuth 2.1 and OpenID Connect authentication provider built for developers and software teams shipping modern web and API-based applications. Hosted in Finland by an EU-owned company, all user identity data remains in the EU and outside US jurisdiction, directly supporting GDPR compliance and data sovereignty requirements. Core authentication methods include passkeys (WebAuthn/FIDO2), magic links, and PIN codes, eliminating passwords entirely. First-time sign-in creates the user account automatically, removing any separate registration step. Enterprise SSO via OIDC connects to Microsoft Entra ID, Okta, Google Workspace, and any SAML or OIDC-compatible provider, with unlimited connections on all plans. SCIM provisioning automates user lifecycle management for enterprise customers. Social login covers Google, GitHub, Microsoft, Facebook, LinkedIn, X, and Discord.

Multi-tenancy support provides isolated user pools, per-tenant branding, and custom domains, making Authalla suited for SaaS teams serving business customers. Full white-labeling, including custom domain, custom email sender, custom colors and logo, and zero vendor branding, is available on every plan including free. Hosted sign-in pages are managed by the vendor; applications integrate via standard OAuth 2.1/OpenID Connect redirect flows. A Management API with scoped API keys supports infrastructure-as-code provisioning. Sign-in hooks attach roles, plans, or custom claims to tokens. Session control allows viewing and revoking sessions per device. Admin impersonation uses the RFC 8693 act claim. Audit logs cover sign-ins, admin actions, SCIM events, and Management API calls, with sign-in charts filterable by time range, tenant, and event type.

An MCP server at api.authalla.com/mcp enables AI coding assistants, including Claude Code, Codex, VS Code, and Zed, to create tenants, configure clients, set custom domains, and apply branding without manual dashboard interaction. Documentation is published as a single llms-full.txt file for agent consumption. Authalla also supports sign-in and scoped access token issuance for user-facing MCP servers and APIs (RFC 8707, RFC 9068), allowing end users to authorize AI agents such as Claude or ChatGPT and revoke access per agent. Pricing is flat and predictable, based solely on monthly active users, with no per-connection fees and no feature gating across plans. Paid plans include direct founder support.
