The downsides with passkey

Google’s Passkey, that we wrote about earlier, is a new password-free service that allows users to log in to their Google accounts using biometric authentication and device verification. While this service offers a more secure and convenient way to access accounts, there are some downsides that users should be aware of.

Reliance on Biometric Data

Passkey relies heavily on biometric data, such as fingerprint or face recognition, to authenticate users. While biometric authentication is harder to replicate or steal than traditional passwords, it is not foolproof. Biometric data can be stolen, and once stolen, it cannot be changed, making it vulnerable to future attacks.

Furthermore, some users may not be comfortable with sharing their biometric data with Google, especially if they have concerns about privacy and security. In the event of a data breach, users’ biometric data could be compromised, which could have severe consequences for the user’s security and privacy.

Limited Availability

Another downside of Passkey is that it is currently only available for Google accounts, which limits its usefulness. While Google accounts are widely used, many users have accounts with other services that do not offer password-free authentication. This means that users still need to remember multiple passwords for different accounts, which can be a hassle and a security risk.

Technical Limitations

Passkey also has some technical limitations that could affect its usability. For example, biometric authentication may not work in certain situations, such as when a user is wearing gloves or has wet hands. In these cases, users will need to use a backup method, such as a PIN code or another biometric method, which could be less convenient and more time-consuming.

Finally, Passkey may not be compatible with older devices or devices that do not have the necessary hardware or software to support biometric authentication. This could limit the number of users who can take advantage of the password-free authentication offered by Passkey.


In conclusion, while Passkey offers a more secure and convenient way to access Google accounts, there are some downsides that users should be aware of. These include a heavy reliance on biometric data, limited availability, and technical limitations that could affect its usability. While Passkey is a step in the right direction for password-free authentication, it is not a perfect solution, and users should carefully consider the risks and benefits before using it.
