Digital Identity
The collection of accounts, credentials, and data points that represent you online, often more fragmented and less controllable than your identity in the physical world.
Your digital identity is distributed across every service you have ever signed up for, often linked by a single email address or phone number that becomes a de facto master key. Unlike a physical ID, there is no single authority you can approach to see or correct the whole picture.
Why it matters: consolidating everything under one identifier is convenient but creates a single point of failure — compromise that one login and an incidenter can pivot into many services.
