IDEE GmbH

IDEE GmbH builds AuthN, a passwordless, phishing-resistant multi-factor authentication platform. Instead of passwords or traditional OTP-based MFA (both vulnerable to phishing and credential theft), AuthN uses a user’s smartphone as the authentication factor: client-side, hardware-generated asymmetric cryptography combined with biometric unlock (via the “OneClick” flow) grants access to a website, application, or workstation, with private keys never leaving the device. The company markets this as a “100% phish-proof” approach, a strong claim that should be read as the vendor’s own framing of its cryptographic design rather than an independently certified guarantee against every phishing technique.

Founded in 2015 and headquartered in Munich, Germany, IDEE has raised a modest $5.99 million in Series A funding to date and operates with an estimated 11-50 employees. The company has picked up positive recognition on G2, a crowd-sourced software review platform, for its passwordless authentication category — a real but vendor-review-driven signal rather than an independent lab evaluation.

IDEE competes in the increasingly crowded passwordless/phishing-resistant authentication space alongside far better-funded players such as Beyond Identity, Transmit Security, and HYPR, as well as the passwordless features built into Microsoft Entra ID and Okta. IDEE’s underlying cryptographic approach (client-side asymmetric keys plus biometric unlock) reflects sound, FIDO-adjacent security engineering principles, but its limited funding and small team size constrain how aggressively it can compete for enterprise deployments against those larger, more heavily marketed rivals.
