Password Less Authentication by using Physical Keys ? and its Benefits
Passwordless authentication is a type of security measure that allows users to access their accounts or devices without needing to enter a password. Instead, users can authenticate themselves using a variety of methods, such as biometric factors like fingerprints or facial recognition, or by using a physical security key.
Physical security keys are small, portable devices that can be used for passwordless authentication. They typically come in the form of a USB key or smart card and are equipped with a secure element, such as a dedicated microprocessor, that stores the user’s authentication credentials.
Using a physical security key for passwordless authentication can provide several benefits:
One of the main benefits is increased security. Because a physical security key is a hardware-based device, it is much harder for attackers to compromise than a password, which can be easily guessed or stolen. Additionally, physical security keys often use strong cryptographic algorithms to ensure that the authentication process is secure.
Another benefit of using a physical security key for passwordless authentication is increased convenience for users. Because they don’t need to remember a complex password, users can easily and quickly authenticate themselves using the security key. This can be especially useful for users who have difficulty remembering complex passwords or who need to access their accounts or devices frequently.
Recent years its very effective against the ransomware type of attack against sensitivities assets like production servers, storage and sensitive identity managed environments
However, there are also some limitations to using a physical security key for passwordless authentication. One potential limitation is cost. Physical security keys can be more expensive than other authentication methods, such as password-based authentication or biometric authentication using a smartphone or other device. Additionally, users may need to purchase multiple security keys if they want to use them on multiple devices or accounts.
Another potential limitation is availability. Not all devices and platforms support physical security keys, so users may need to use a different authentication method if they want to access their accounts or devices on a device that doesn’t support the security key. Additionally, users may need to carry the security key with them at all times in order to use it for authentication, which can be inconvenient.
Overall, using a physical security key for passwordless authentication can provide increased security and convenience for users, but there are also some potential limitations to consider.
