# What is Passkey and How Does It Work? The era of passwordless authentication is here. - **Source:** [Hacking Humans](https://brifing.si/source/5c2a25b7-81b2-4f80-9066-74997292410d) - **Published:** 2026-09-01 - **Topic:** [Data & AI](https://brifing.si/c/data-ai) - **Original article:** - **On Brifing:** https://brifing.si/s/a625058a-75b1-4d6a-b680-24df89724e43 ## Definition of Passkey Passkey is a passwordless authentication protocol based on the FIDO2 standard. It replaces traditional passwords, offering a more secure login experience. Instead of complex passwords, it uses device-based verification methods. This approach significantly reduces the risk of cyber attacks. ## How It Works Passkey uses a key pair stored on the user's device (phone, computer, etc.) for authentication. During login, the device verifies identity using this key. Biometric data (fingerprint, facial recognition) or PIN codes are used for verification. This process is resistant to phishing attacks. ## Google and Passkey Google announced passkey support in 2023. Users can now use this method for their Google accounts. This move is seen as a significant step toward a passwordless future. Google is collaborating with other platforms to promote passkey adoption. ## Advantages Passkey enhances security while improving user experience. It eliminates the risk of forgotten or stolen passwords. It also offers a more secure alternative to single sign-on (SSO) solutions. Its adoption in corporate environments is expected to grow. ## FIDO2 Standard Passkey is based on the FIDO2 standard developed by the FIDO (Fast Identity Online) Alliance. This open-source protocol is widely accepted in the industry. Tech giants like Microsoft, Apple, and Google support FIDO2. The standard ensures cross-device compatibility. ## Use Cases Passkey has a wide range of applications, from e-commerce platforms to banking apps. It is particularly favored in high-security sectors. It provides an ideal solution for mobile apps and websites. Security is maintained even if users lose their devices. ## Future Projections Passkey is expected to become widespread within the next 5 years. It can be used alongside password managers and two-factor authentication tools. Experts predict that passkey will revolutionize cybersecurity. Although changing user habits will take time, it will eventually become the standard. ## Why It Matters Passkey marks the beginning of a new era in digital identity management. It addresses the weaknesses of traditional passwords. It offers a more secure and user-friendly experience. For businesses, it reduces the risk of data breaches and lowers costs. ## Sources covering this story - https://thecyberwire.com/podcasts/word-notes/149/notes — --- _Summary written by Brifing from the original reporting.
