3FBA

3FBA is an acronym that can refer to several different concepts or entities. There is no single, widely recognized definition of 3FBA, and the meaning is domain-dependent.

In technology and security contexts, 3FBA is sometimes used informally to denote a three-factor authentication scheme that extends the standard “three factors” by emphasizing biometric components; however, the standard term is three-factor authentication (3FA), and 3FBA is not standardized.

In other domains, 3FBA may be used as a project code, an organization abbreviation, or a brand name associated with a specific company, community group, or research initiative. Because it is ambiguous, readers are advised to consult the source defining 3FBA to determine its precise meaning in that context.

If you encountered 3FBA, examine surrounding text for domain cues (technology, finance, biology), look for official documentation, and check for a defined expansion (for example, “Three-Factor Biometric Authentication” or a named organization).
