How to Find the Right Authentication Solution
Kate Bennett • October 20, 2026

Choosing the Right Solution can be Complicated

There are more ways to authenticate than ever before: passwords, smart cards, biometrics, mobile credentials, security keys, passkeys, FIDO2 authentication, and certificate-based credentials. Organizations are looking for MFA solutions that are not only secure, but also phishing-resistant, easy to deploy, compatible with existing infrastructure, and practical for their users.


So how do you determine which authentication technology is right for your organization? At Tx Systems we always start with the use case. Our team will: build authentication strategies around specific requirements by evaluating organizations systems, identifying compatible hardware and software, and testing solutions. Whether you're evaluating hardware-based passkeys, smart card authentication, biometric authentication, FIDO2 authentication, or another MFA solution, our team will help you find the right fit.

Authentication Solutions for Every Use Case

FIDO2 Authentication & Hardware-Based Passkeys

FIDO2 authentication (passkeys) provide a phishing-resistant approach to passwordless security by using cryptographic credentials instead of passwords. Hardware-based FIDO2 security keys, smart cards, and passkeys can provide a strong authentication factor for employees, administrators, privileged users, and other high-value accounts. Tx Systems can help organizations evaluate FIDO2 solutions for environments such as Microsoft Entra ID and identify the right combination of credentials, readers, and supporting software.

MFA Solutions

Multi-factor authentication (MFA) adds additional layers of protection by requiring users to verify their identity using factors such as something they know, something they have, or something they are. MFA solutions can include security keys, smart cards, biometrics, mobile credentials, and other authentication technologies. Tx Systems helps organizations identify MFA solutions that balance security, usability, compatibility, and deployment requirements.

Smart Card Authentication

Smart card authentication remains a proven solution for organizations that require certificate-based authentication, strong identity assurance, or specialized credentials such as CAC and PIV. Smart cards can support Windows login, VPN access, applications, physical access, and other use cases. Tx Systems can help organizations select the appropriate cards, readers, middleware, and authentication software for their environment.

Biometric Authentication

Biometric authentication uses characteristics such as fingerprints or facial recognition to verify a user's identity. Biometrics can provide a convenient authentication factor while reducing reliance on passwords and physical credentials. Tx Systems can help organizations evaluate biometric readers and authentication technologies based on their security requirements, operating environment, and user experience.

NFC, RFID & Contactless Authentication

NFC, RFID, and contactless credentials provide convenient authentication options for organizations that want users to authenticate by tapping or presenting a credential. These technologies can support logical access, physical access, identification, and converged credential applications. Tx Systems offers a range of contactless readers and credential technologies and can help determine which option best fits the application.

Converged Credentials

Converged credentials combine physical and digital access capabilities into a more unified identity experience. Instead of maintaining separate credentials for building access and computer authentication, organizations can use technologies that support multiple access requirements through a single credential. Tx Systems can help organizations evaluate converged credential strategies that bring together physical access, logical access, smart cards, RFID, NFC, and FIDO2 technologies.

Embedded Authentication

Embedded authentication solutions integrate readers and authentication technology directly into equipment such as printers, kiosks, medical devices, workstations, and specialized systems. These projects often require more than an off-the-shelf product and may involve hardware integration, testing, configuration, and technical documentation. Tx Systems can help organizations evaluate and implement authentication hardware designed specifically for their application.

CAC & PIV Authentication

CAC and PIV authentication is commonly used in government, defense, law enforcement, and contractor environments where strong credential-based authentication is required. Tx Systems provides CAC/PIV-compatible readers, adapters, and authentication technologies that can help organizations integrate these credentials into computers, applications, mobile devices, and specialized systems.
