username.md

username.md offers a unified digital profile designed for people, applications, and AI agents. Users can claim a personal page at username.md/name that functions as a readable verified digital identity profile, an email forwarding address to manage communications, and a verifiable API that allows third parties to confirm identity. It simplifies online presence by consolidating verification, contact, and discovery into a single universal @address. Username provides the users handle as a subdomain, so users get their own web:did address without the hassle of owning an apex domain. Users get Answer Engine Optimization and Generative Engine Optimization included with their name registration. Agents speak native A2A or SAM or MCP. Additionally, an llms.txt file is provided. An example can be seen at: https://chris.username.md USERNAME.md also offers SSO as a Service (SSOaS) an industry first.
