Our technology stack is based on SSI, a new internet protocol that will change the way identity data and authentication is shared between entities, users & devices.

SSI is a protocol defined in the for exchanging data in a decentralised way: it combines data and ownership into one single dataset, then signs the dataset by using digital signatures and puts the content into an object called Verifiable Credential (VC).

SSI is a standard and therefore is meant to be interoperable, as long as different providers implement the same rules defined in the definitions. We comply with W3C as well as with EBSI & eIDAS 2.0 (EU DI).

A VC, describes not only a set of data, but also contains its ownership through a signature. Similar to digital signatures, a VC can be verified at a later point and therefore trusted.

Every unambiguous attribute/specification that represents a user or device can be a VC: a KYC/ ID data set, a public key, a payment method, a medical exam, a degree or certification, and many more.

sideos Base (incl. Passwordless Login)


Our middleware API connects an organisation’s decentralised data to other trusted data sources to verify the data being requested is legitimate. In a second step we replace passwords, PINs, tokens, physical keys, cards etc. The API is very lean with only 2 endpoints.



sideos provides an SDK to be integrated into mobile apps for Android and iOS. The SDK enables the app to interact with the SSI protocol and capture, store, and share Verifiable Credentials.

Mobile Wallet:

Our mobile SSI wallet is available for Android and iOS and can be used to interact with W3C-compliant SSI services. Links Apple & Google

Backup & Recovery

Over the past decades, account recovery has been a difficult and user-unfriendly thing, from SMS OTPs to call center interaction. Back-up & recovery with sideos is easy, secure and unbreakable.
