What is physical security key?
A physical security key is a type of hardware-based authentication used to verify account access and transactions. Unlike software-based options, physical security keys work offline and are not reliant on cloud services, minimizing risks like account takeovers or unauthorized access.

Notes
Why choose physical security key?
A physical security key provides an additional layer of protection, especially against potential vulnerabilities in software-based options like authenticator apps and passkeys. While software-based options offer convenience, they also come with potential risks:
Authenticator apps: if synced with cloud accounts (e.g., Google or Microsoft), losing access to the account could expose the authenticator. Device theft also poses a threat if lock-screen security is compromised
Passkeys: while more secure than passwords, they rely on third-party account synchronization and can be accessed if the linked device is stolen and unlocked
