Can your fingerprints be stolen from a smartphone? (2024)

Welcome to Blackview (The leader of rugged smartphone) blog. Hope the guide helps.

Yes, it is possible for your fingerprint to be stolen from your phone. There are a number of ways that this could happen, including:

Fingerprint scanners that are not properly protected: If a fingerprint scanner is not properly protected, a hacker could use a technique called "smudge attack" to lift your fingerprint from the scanner. This can be done by placing a piece of tape over the scanner and then pressing your finger against it. The tape will pick up the ridges of your fingerprint, which can then be used to create a fake fingerprint.
Malware: If you install malware on your phone, it could be able to steal your fingerprint data. This could then be used to unlock your phone or to access other sensitive data.
Data breaches: If the data from your phone is breached, your fingerprint data could also be stolen. This could happen if a company that stores your phone data is hacked, or if your phone is lost or stolen and the data is sold on the black market.

While it is possible for your fingerprint to be stolen, there are a number of things you can do to protect yourself:

Use a strong PIN or password: This will make it more difficult for someone to access your phone even if they have your fingerprint.
Keep your phone software up to date: This will help to protect you from known security vulnerabilities.
Avoid using fingerprint scanners that are not properly protected: If you are concerned about the security of your fingerprint scanner, you can choose to use a PIN or password instead.
Be careful about what apps you install on your phone: Only install apps from trusted sources, and be careful about giving apps permission to access your fingerprint data.
Be aware of data breaches: If you are ever notified of a data breach, be sure to change your PIN or password immediately.

By following these tips, you can help to protect your fingerprint data and keep your phone secure.
