What Are the Advanced Authentication Methods in IAM and CIAM?

Advanced authentication improves your security. And when paired with an IAM you have lower administrative costs and much better visibility - and here’s what you need to know about it.

What are Advanced Authentication Methods in IAM and CIAM?

In Identity and Access Management (IAM) and Customer Identity and Access Management (CIAM) advanced authentication are typically security frameworks that add layers and help tighten security. Some of these include passkeys, Multifactor authentication, and even token-based authentication.

One good example of token-based authentication would be a Windows Authentication framework. However, when using your authentication framework having systems in place like conditional access based on your own policies is what makes all the difference in user experience.

While the word advanced may make it sound complicated - in reality they are simple security frameworks in place that can boost security and your existing compliance practices by automating them or in many cases just adding additional specific layers of security.

1. Passkeys

Passkeys are one advanced authentication method that replaces traditional passwords with a more secure and user-friendly alternative.

This authentication method relies on cryptographic keys stored securely on user devices, such as smartphones or computers, to authenticate access. This eliminates the risks associated with password theft or reuse.

Passkeys also support device-based authentication, like biometrics or PINs, for added security. Their use simplifies login processes while meeting industry standards for secure access management.

Types of Passkeys

Biometric Passkeys: Authentication through fingerprint, facial recognition, or iris scans stored securely on the device.
Device-Based Passkeys: Cryptographic keys tied to a specific device, such as a smartphone or security token. One good example of this would be apple passkeys.
Pin-Based Passkeys: Short numerical codes used with a device for authentication.

Hardware Security Keys: These are typically physical devices, like USB keys, that generate or store passkeys for secure access.
App-Generated Passkeys: These are temporary codes created by authentication apps for one-time use.

Advantages of Passkeys
