privacyIDEA Authenticator by NetKnights GmbH offers a robust multi-factor authentication solution that enhances security without compromising user experience.

privacyIDEA is a modular solution designed for two-factor authentication, particularly with OTP tokens. It offers multi-tenancy and multi-instance capabilities. The modular structure of privacyIDEA allows for easy adaptation and enhancement. For instance, adding new token types is streamlined by creating a new lightweight Python module. No alterations to your network are required for privacyIDEA, as it does not write to existing databases or user stores but solely requires read access to user stores such as LDAP, Active Directory, SQL, SCIM-service, or flat files. Workflows can be augmented without necessitating modifications due to its straightforward REST-like API, facilitating automation and seamless integration.

The "privacyIDEA Authenticator" smartphone app transforms your smartphone into an authentication device that seamlessly interfaces with the privacyIDEA backend. Unlike traditional smartphone-based tokens, the privacyIDEA Authenticator offers a more secure rollout process. Besides supporting HOTP and TOTP authentication methods, the privacyIDEA Authenticator also enables authentication via push notifications.
