-## Fingerprint
-
-Enrol under **Settings → Users** (Plasma's own fingerprint page; the `fprintd`
-command-line tools are not installed, fingerprintd replaces that package).
-**Hold** the finger on the sensor for each of the ~20 presses rather than
-tapping it; a held press is what the matcher was measured on.
-
-Two things to know:
-
-- The lock screen listens for a finger for **60 seconds after it appears**.
-  A press after that reaches nothing and looks like a dead sensor. Lock and
-  unlock again to re-arm it.
-- The matcher is the phone's own proprietary trustlet, reassembled from the
-  stock modem partition on first boot and never shipped by us. Templates are
-  stored on the Android `persist` partition, sealed to the same hardware
-  anti-rollback counter stock Android uses. Whether fingerprints enrolled under
-  stock Android survive a return to it after using this has **not** been
-  tested.
-
-A finger can also run something in your session on a match
-(`~/.config/fingerprintd/fingers.conf`, see the fingerprintd README).
