myId

myId is a generic term used in software development to denote a unique identifier associated with an entity, most commonly a user, an account, or a resource. It is frequently used as a field name in data models and as a placeholder in API and code examples. It is not meant to convey human-perceived information.

In practice, a myId can take several forms, including numeric IDs, alphanumeric strings, or universally unique identifiers (UUIDs). The choice depends on the system’s requirements for scalability, privacy, and interoperability. Unlike a username or display name, a myId is intended to be stable and not typically shown to end users.

In web APIs, myId often appears as a path parameter or query parameter used to fetch, update, or delete a resource. Example: GET /users/{myId} or GET /resources/{myId}/details. When used in URLs or logs, exposing internal IDs can raise privacy and security concerns; some systems replace IDs with opaque tokens.

Best practices include using clear naming (for example userId rather than myId in code), using UUIDs when global uniqueness is required, and enforcing proper authorization to ensure that a given myId corresponds to a resource the caller is allowed to access. Do not rely on sequential IDs for security by obscurity.
