A woman in Castleford, UK, discovered that a £2.70 ($3.40) full screen protector for her Samsung Galaxy S10 allowed everyone access via the thumbprint authentication.
Thumbprint authentication is now a widely used form of security, also used in essential services such as online banking. Phone manufacturers and users alike put a lot of faith into it, so any failures cause serious concern.
The latest Samsung Galaxy S10 comes with an in-display fingerprint reader. This technology was announced a long time ago, but it took a while for manufacturers to make it work. The placement of the new fingerprint reader means that Samsung can leave the back of the phone clear, except for the camera.
