Setting up fingerprint
authentication
Your terminal features a fingerprint sensor
O
( ). Once you register your fingerprint for
O
, you can touch the key with your finger
to unlock the screen (fingerprint
authentication).
Notes on using fingerprint
authentication
Your terminal recognizes a fingerprint based
･
on its unique characteristics. For this reason,
some users may not be able to use fingerprint
authentication if their fingerprints are not
sufficiently unique.
Authentication performance—how
･
successfully your fingerprint can be
recognized when you touch the fingerprint
O
sensor ( ) properly—varies depending
on the condition of your fingers. Fingerprint
registration may fail or the authentication
performance may decrease if your fingers
have any of the conditions listed below. Note
that you may be able to improve the
authentication performance by wiping or
washing your hands, using a different finger
for authentication, or registering a larger area
of your fingerprint.
- Your fingers are: Wrinkled or wet (for
example, after you take a bath)
