Note that the URL https://help.ubuntu.com/stable/ubuntu-help/session-fingerprint.html
refers to the latest stable release (currently Ubuntu 19.04) The URLs to the 18.04 docs is: https://help.ubuntu.com/lts/ubuntu-help/session-fingerprint.html or https://help.ubuntu.com/18.04/ubuntu-help/session-fingerprint.html Now that doesn't help; apparently the 18.04 docs is a bit insufficient for 18.04. However, it would be too much work to go back and change the 18.04 docs, so closing. @Mustafa: If you have problems to make it work, it's probably a support matter or a bug against some other package, i.e. not a docs bug. You may want to ask a question at e.g. <https://askubuntu.com> to get help and find out. ** Package changed: ubuntu-docs (Ubuntu) => gnome-user-docs (Ubuntu) ** Changed in: gnome-user-docs (Ubuntu) Status: Confirmed => Won't Fix -- You received this bug notification because you are a member of Documentation Packages, which is subscribed to ubuntu-docs in Ubuntu. https://bugs.launchpad.net/bugs/1787974 Title: Fingerprint authentication not available in 18.04 Status in gnome-user-docs package in Ubuntu: Won't Fix Bug description: This page describes a feature not found in 18.04 https://help.ubuntu.com/stable/ubuntu-help/session-fingerprint.html.en Starting from point 3. "Press on Disabled, next to Fingerprint Login to add a fingerprint for the selected account. If you are adding the fingerprint for a different user, you will first need to Unlock the panel." The option "Fingerprint Login" isn't available in the GUI (not displayed at all). The following steps to enroll fingers are therefore missing as well.
