What VoxKey is
VoxKey is a free, open-source authentication platform that developers can self-host for SaaS, AI, and B2B applications. It runs through the web and supports OAuth 2.1, OpenID Connect, and SAML. Sign-in options include passwords, social providers, and one-time codes delivered by email or SMS. Multi-factor authentication can use passkeys, authenticator apps, or backup codes. Enterprise SSO connections include Okta, Entra, SAML, and other identity providers. VoxKey organizes tenants as realms, separating users, providers, keys, and configurations, with a central dashboard for administration. Role-based access control covers global and organization-level resources. Built-in social providers include Google, GitHub, Discord, Yandex, and Steam, while OAuth2- or OIDC-compatible providers can be added. Account linking uses verified email and OTP conflict resolution. Social identity data is stored, but provider OAuth access tokens are not supplied for calling provider APIs.
Who it suits
VoxKey suits developers building SaaS, AI, and B2B applications that need self-hosted workforce authentication. It also fits teams seeking multi-tenant realms, enterprise SSO, and authentication policies.
What it does well
- Free and open-source deployment model
- Supports OAuth 2.1, OpenID Connect, and SAML
- Passwordless codes and multiple MFA options
- Per-realm separation of users and keys
- Built-in social providers and extensible integrations
What to know first
- Self-hosted deployment requires running the service
- No directory synchronization is listed
- Provider OAuth access tokens are unavailable
Verdict
VoxKey combines self-hosted authentication with standards support, passwordless sign-in, MFA, SSO, and realm isolation. Its lack of directory sync and provider API access tokens may matter for some implementations.
