Identity, examined.

Automotive identity spans owners and drivers in connected-car apps, a large dealer and supplier network, and the cryptographic identity of vehicles, ECUs, and backends, all under UN Regulation No. 155 and ISO/SAE 21434.

Crypto identity combines self-custodial wallet authentication such as Sign-In with Ethereum, decentralized identifiers and verifiable credentials, and bank-grade KYC under the FATF Travel Rule and MiCA, while defending users against wallet drainers and seed-phrase theft.

Education identity has to serve students, staff, parents, researchers, and alumni at once, keep app rosters in sync through OneRoster or Clever, and protect student records under FERPA and children's data under the amended COPPA Rule.

Energy and utility identity protects critical infrastructure where a compromised account can have physical consequences. This guide covers OT privileged access, remote access, and what NERC CIP and NIS2 require of identity programs.

Manufacturing identity spans the plant floor and the supply chain: privileged access to operational technology, machine identity for connected equipment, and governed access for suppliers and integrators, under IEC 62443 and NIS2.

Streaming identity ties login directly to revenue: it enforces households and paid sharing, limits concurrent streams, separates profiles, signs users in on TVs through the device authorization grant, and has to hold up against credential stuffing at massive scale.

Progressive profiling replaces the long signup form with small, well-timed questions asked when the answer is actually needed. How the pattern works, where the data comes from, how to implement it in CIAM, and how to keep each step compliant.

Social login lets customers sign up with an account they already have at Google, Apple, or another provider. What it gains you, the account-linking and dependency risks most teams miss, and how to implement it correctly with OpenID Connect.
