We will acquire a fingerprint that we will store temporarly to test if the reader works properly.

 1. Acquire the fingerprint with the command
{{{
sudo tf-tool --acquire
}}}
It will ask for your fingerprint 3 times (or more if there are failed scans).

 2. Test your fingerprint
{{{
sudo tf-tool --verify
}}}
It will tell you if the scan match the one acquired above.

A typical test session is something like that :

Use it everyday !

Known problems

F.A.Q

  • Can I still use a regular password ?

  • Yes. The "enter your password" will be replaced by "Enter your password or swipe your finger". You can still use your password if you are wearing gloves (just an example)

  • I have a "Could not claim USB device" error

  • You must run tf-tool as root or use "sudo" in front of the command.
