Your fingerprints can be lifted from photos. Here's what to actually do about it. 1. Be mindful of hand photos. high-resolution photos of your fingertips at close range are the risk. a normal selfie or group photo is not. The concern is clear: close shots of your fingers, peace signs, hands holding items, and typing shots. 2. Don't rely on fingerprint authentication alone for high-stakes accounts. Use a strong PIN or password as your primary unlock method. fingerprint as convenience, not as your only lock. 3. Use a passkey or hardware security key for your most sensitive accounts. These cannot be spoofed from a photo. 4. For banking apps: enable a secondary PIN in addition to biometric. Most banking apps support this. Use it. 5. Know your threat model. For most people, a spoofed fingerprint attack requires physical access to your device afterward. The photo gets the print. The attacker still needs to be holding your phone. If you're not a high-value target, your risk is low. If you are a high-value target: Disable fingerprint authentication entirely on your most sensitive devices. Use a long alphanumeric PIN. Assume any high-resolution photo of your hands is a liability. Your fingerprint is the one password you can never change. treat it accordingly.
