In this case, one speaks of social login. For example, numerous web services integrate the “Continue with Facebook” login option, in which the user authenticates himself with his Facebook identity. Other social login providers include Twitter, LinkedIn, and others. Identity providers can also be banks, government institutions, network, and Internet providers, or commercial identity service providers.

With these providers, the basis for creating a certified digital identity is often a strict identity check, for example, by means of ID or in the context of personal, physical presence. In principle, completely autonomous ID management by the end-user himself or decentralized management of digital identities via blockchain technology is also conceivable.
