identifikationskod

Identifikationskod, or identification code, is a term used in Swedish to describe a code that uniquely identifies an individual, organization, or device within a system. It serves as a key for recognizing and addressing a user or entity and is commonly used for authentication, record linkage, and access control. An identifikationskod can be numeric or alphanumeric, and its format, length, and issuing authority vary depending on the context and organization. Examples include personal codes such as PINs, customer numbers, employee IDs, or service-specific codes. In many online and offline services, a identifikationskod is used together with another credential, such as a password, biometric data, or one-time codes, as part of multi-factor authentication.

The lifecycle of an identifikationskod is typically managed by the issuing organization and may involve creation, assignment, change, deactivation, or revocation. In some systems, the code is permanent; in others, it can be rotated or invalidated if suspected of compromise. Privacy and security considerations include restricting access to the code, ensuring secure transmission and storage, and avoiding sharing.

The term is widely used in Swedish contexts, but similar concepts exist under different names in other languages. It should not be confused with a personal identity number or other official identifiers that have legal definitions and protections. A well-designed identifikationskod balances usability with security, and is treated as sensitive information by organizations that handle it.
