FIDO2 standards

FIDO2 standards refer to a modern and secure way of logging into systems that does not require traditional passwords. Instead of entering a password, which can be compromised or stolen, the user authenticates with a physical device. In the context of POS systems, FIDO2 is used to securely log operators, such as cashiers or managers, into the POS. The login works by the system sending a prompt and the device, in this case a reader, responding with a unique digital signature that cannot be copied. This signature verifies the user's identity without sending any password over the network. This is not a technology for processing payments from customers, but solely a method for verifying the identity of staff when they log into the facility.
