Web3, Decentralized autonomous organizations, Identity, Ethereum address

Web3 solves these problems by allowing you to control your digital identity with an Ethereum address and ENS profile. Using an Ethereum address provides a single login across platforms that is secure, censorship-resistant, and anonymous.

I am tormented by seditious thought: the use of a unique and single address of that Ethereum is not the same "Permanent record", utmost centralization, the authentication token, but created and presented by the very man and by his own will?

Zero-knowledge proofs, however, can simplify authentication for both platforms and users. Once a ZK-proof has been generated using public inputs (e.g., data attesting to the user's membership of the platform) and private inputs (e.g., the user's details), the user can simply present it to authenticate their identity when they need to access the service. This improves the experience for users and frees organizations from the need to store huge amounts of user information.
