JDOE

jdoe is a placeholder username commonly used in computing and documentation to represent a generic or anonymized user account. It appears in sample data, tutorials, test environments, and demos where real identities should not be revealed.

The practice of using jdoe stems from the broader placeholder name John Doe, used in English law and folklore to denote an unnamed or typical person, with Jane Doe as a female counterpart. The form jdoe arises from a common UNIX-style convention of combining an initial with a surname, producing a simple, lowercase identifier.

As a result, jdoe is common in UNIX-like systems when illustrating commands, access control, or account management; it may appear in /etc/passwd, sample scripts, or documentation. In tutorials and test environments, it serves as a stand-in for a real user without exposing individuals.

Usage, privacy, and variants: In examples, jdoe stands in for a user; in data anonymization, records may substitute real names with jdoe; in testing, automated scripts may create a jdoe account for privilege testing. To avoid ambiguity, some guidelines prefer descriptive placeholders or generated tokens in production data.

Variants include john.doe, jdoe1, or j.doe, depending on naming conventions and the need for uniqueness. When used in real datasets, organizations should redact or replace with non-identifying tokens. See also John Doe; Jane Doe; placeholder name; test data.
