OpenOTP Authentication Server is an authentication and identity management solution for multi-factor access, offered for cloud or on-premise deployment. It supports mobile push, smart-card certificates, secure magic links, YubiKey, FIDO2 passkeys and software tokens, alongside factors such as SMS, email, hardware tokens and OATH. Federated access options include SAML, OIDC and OAuth. Directory and identity integrations include Active Directory, LDAP, Entra ID, Okta, Google, Ping Identity and One Identity. The server also provides EAP network access control, mobile electronic signatures and mobile badging. Windows and macOS login plugins are listed, as are PAM plugins for Linux and macOS. OpenOTP is a WebADM sub-package and cannot be installed standalone.

The Freeware plan costs nothing and includes documentation and forum support only.
