# Decentralized Identifiers (DIDs)

> Universal ID for both human and agent

[DIDs](https://www.w3.org/TR/did-1.1/) are a core component of the W3C's Verifiable Credentials standard and enable secure, private, and verifiable digital identity.When you first onboard to the T3N Network, the network automatically generates your unique `did:t3n` identity. Every entity in the network whether a human user or an AI agent is assigned a unique Decentralised Identifier (DID).

The format of a DID in T3N is: `did:t3n:<unique-id>`. Key properites and uses include:

* It's a permanent address on the network, linked to authentication methods and permissions.
* Used to access and manage your data and TEE contracts.
* Only binded to one user profile or agent.
* Each DID can hold a T3N [token](/t3n/how-t3n-works/tokens) balance.
