With TK-Ident you can log in to digital health applications.

Features & Capabilities

TK-Ident is a Chrome extension that enables secure authentication for digital health applications using your TK Health ID. Create and use your TK Health ID, log in to TK-Safe, and manage your devices and consents from one place. Access health services conveniently from your smartphone, anytime, anywhere.

Security and ongoing development: Accessing sensitive health data requires high security. TK-Ident uses strict identification methods—online ID with PIN or health insurance card—and periodic re-identification to protect your information. The project adheres to rigorous legal requirements and is continuously improved with user feedback (service@tk.de). Accessibility is a priority, with an accessibility statement available at https://www.tk.de/techniker/2026116.

User Reviews

Users broadly report TK-Ident as buggy and unreliable, especially on GrapheneOS/custom ROMs, with persistent 'Unexpected error' messages and NFC/ID card scanning failures. Privacy and security concerns arise due to reliance on Google's Play Integrity API and US services. Overall usability is poor, featuring a convoluted workflow and repeated errors, and there are few or no workable alternatives for non-standard Android distributions.

Pros

Cons

Incompatibility with GrapheneOS and other custom ROMs; app cannot be used on secure distributions
Frequent 'Unexpected error' or 'an error occurred' messages during registration and use
NFC card scanning / ID card reading fails or stops at 15% despite repeated attempts
Reliance on Google Play Integrity API and other US services leading to privacy concerns and vendor lock-in
Poor usability and a confusing, error-prone workflow with duplicated steps and unclear guidance
