What does electronic authentication (e-authentication) establish?

Electronic authentication (e-authentication) is a fundamental process in identity and access management that establishes trust in the identities of users who present themselves electronically. By verifying the authenticity of a user's identity through various means—such as passwords, biometrics, digital certificates, or other authentication factors—e-authentication ensures that only legitimate users gain access to systems, applications, or sensitive information.

This trust is crucial for securing digital interactions, especially in environments where sensitive data is handled. Establishing confidence in user identities helps protect against unauthorized access and potential breaches. It underpins the security framework necessary for online transactions, data sharing, and any operations relying on digital identity verification.

The other options provided do not align with the primary purpose of e-authentication. Access to physical locations involves different methods and often physical credentials, while user preferences and behaviors focus on user analytics, not identity validation. Network management protocols pertain to the administration and performance of network resources, which is separate from the concept of verifying user identity.
