A **Trust Service Provider (TSP)** is an organization that provides secure digital services enabling trust and legal certainty in online transactions. TSPs offer essential digital security solutions, such as electronic signatures, [digital certificates](https://www.corbado.com/glossary/microcredentials), secure timestamps, and authentication mechanisms. Trust Service Providers are fundamental to secure digital interactions, playing critical roles including: - **Identity Verification:** Issuing [digital certificates](https://www.corbado.com/glossary/microcredentials) that validate user or entity identities. - **Electronic Signatures:** Providing legally recognized electronic signatures for secure document signing. - **Timestamping:** Offering trusted timestamps to verify precisely when digital documents or signatures were created. - **Authentication Services:** Delivering secure, reliable authentication solutions including multi-factor authentication, biometrics, and passkeys. TSP services are particularly crucial for sectors that handle sensitive information or require high trust levels, such as finance, [healthcare](https://www.corbado.com/passkeys-for-healthcare), [government](https://www.corbado.com/passkeys-for-public-sector), and [e-commerce](https://www.corbado.com/passkeys-for-e-commerce). Within the European Union, certain TSPs certified under the [eIDAS](https://www.corbado.com/glossary/eidas) regulation are referred to as Qualified Trust Service Providers (QTSPs), offering services that carry explicit legal recognition. > **Key Takeaways:** > > - A **Trust Service Provider (TSP)** delivers secure digital trust solutions, including > electronic signatures, [identity verification](https://www.corbado.com/blog/digital-identity-guide), and secure > authentication. > - TSPs enhance security and provide legal certainty for online transactions. > - Qualified TSPs (QTSPs) are specifically certified under EU [eIDAS](https://www.corbado.com/glossary/eidas) > regulations, offering legally binding digital trust services. --- ## The Role and Importance of Trust Service Providers (TSPs) Trust Service Providers are at the forefront of enabling trust and security in digital environments. As digital transformation accelerates, securing online identities, transactions, and data has become increasingly critical, making TSPs essential for modern digital ecosystems. ## Core Services Offered by TSPs TSPs provide an array of digital trust services that enable organizations and individuals to perform secure and legally recognized digital transactions: - **Digital Identity and Certificates:** TSPs issue [digital certificates](https://www.corbado.com/glossary/microcredentials) to verify the identities of users, services, and devices. Certificates provide a reliable method for proving identity in online interactions. - **Electronic and Digital Signatures:** Digital signatures from TSPs confirm the authenticity and integrity of electronic documents, with advanced or qualified signatures holding legal equivalence to handwritten signatures. - **Timestamping Services:** Secure timestamps provided by TSPs ensure reliable documentation of when transactions or digital events occur, important for legal, regulatory, and compliance reasons. - **Secure Authentication:** TSPs manage secure authentication processes through modern authentication methods like multi-factor authentication, biometric verification, and increasingly, passkeys. ## TSPs, Qualified TSPs, and Regulatory Compliance Under the European Union's [eIDAS](https://www.corbado.com/glossary/eidas) regulation (Electronic Identification, Authentication, and Trust Services), certain TSPs receive a formal qualification as Qualified Trust Service Providers (QTSPs). These [QTSPs](https://www.corbado.com/glossary/qtsp) meet stringent regulatory standards to provide services recognized as legally equivalent across the EU, enhancing cross-border digital transactions and legal interoperability. ## Benefits of Integrating TSP Services with Advanced Authentication Methods Integrating modern authentication solutions, such as passkeys, with TSP services provides several compelling benefits: - **Enhanced Security:** Passkeys leverage cryptographic methods to deliver strong, [phishing](https://www.corbado.com/glossary/phishing)-resistant security, significantly improving trust in digital identities and transactions. - **Improved User Experience:** TSP-provided authentication combined with passkeys eliminates cumbersome passwords, reducing friction and enhancing user convenience, crucial for customer satisfaction and retention. - **Regulatory Compliance and Trust:** Integrating secure authentication methods like passkeys ensures organizations remain compliant with stringent regulations (e.g., [PSD2](https://www.corbado.com/blog/psd2-passkeys), GDPR) while simultaneously improving transaction security and customer trust. ## Example Use Cases for Trust Service Providers TSPs operate extensively across many sectors, enabling secure, legally recognized digital interactions: - **Banking and Financial Services:** TSPs secure online [banking](https://www.corbado.com/passkeys-for-banking) services through digital identities and electronic signatures, protecting sensitive financial transactions. - **Government and Public Sector:** Digital certificates and secure authentication from TSPs allow [governments](https://www.corbado.com/passkeys-for-public-sector) to provide secure, reliable e-[government](https://www.corbado.com/passkeys-for-public-sector) services. - **Healthcare Industry:** Secure timestamping and electronic signatures offered by TSPs protect medical records, e-prescriptions, and patient information, ensuring compliance with regulations. In summary, TSPs represent a foundational component in securing and legitimizing digital interactions across diverse sectors. Their integration with modern authentication technologies like passkeys further strengthens digital security, compliance, and user experience. ## TSP FAQs ### What does a Trust Service Provider (TSP) do?
