EAP (Extensible Authentication Protocol)

EAP (Extensible Authentication Protocol) is a framework used in networks to securely verify the identity of devices or users trying to connect. Think of it as a flexible set of rules that allows different methods—like passwords, digital certificates, or biometrics—to confirm who you are. EAP is commonly used in Wi-Fi networks and VPNs to ensure only authorized individuals gain access. Its "extensible" nature means it can accommodate many different authentication methods, making it adaptable to evolving security needs while maintaining a consistent process for verifying identities.
