Ultimately, the best way to store biometric data depends on the specific needs of the organization or individual. If the data is highly sensitive, then it may be best to store it locally. However, if the data is less sensitive, then it may be more convenient and cost-effective to store it in the cloud.

In the case of your employer, storing fingerprints in the cloud may be more convenient for users, but it also introduces the risk of a data breach. If an attacker gains access to the cloud storage, they could potentially compromise all of the user’s accounts that use fingerprints for authentication.

Multifactor authentication (MFA) can help to mitigate the risk of unauthorized access, even if an attacker has your fingerprints. MFA requires two or more factors to authenticate a user, such as a password, fingerprint, and code sent to a mobile device. This makes it more difficult for an attacker to gain access to an account, even if they have one of the factors.

In the case of your employer, MFA could be used to require users to enter their fingerprint and a code sent to their mobile device to authenticate their login. This would make it more difficult for an attacker to gain access to the user’s accounts, even if they have the user’s fingerprint.

It is important to note that MFA is not a perfect solution. It can be defeated if the attacker is able to obtain all of the factors, such as the user’s password, fingerprint, and mobile device. However, MFA can significantly reduce the risk of unauthorized access and is a valuable tool for protecting online accounts.
