  2. 运行 fprintd-enroll 录入指纹信息,默认是为当前用户录入右食指指纹

    fprintd-enroll
    

    不过你也可以用 -f 选项指定录入哪个手指的指纹

    for finger in {left,right}-{thumb,{index,middle,ring,little}-finger};
    do
        fprintd-enroll -f "$finger"
    done
    
  3. 使用 fprintd-verify 可以验证录入的指纹

    使用 fprintd-list 查看已经录入的指纹

    使用 fprintd-delete 删除已经录入的指纹

  4. 配置 /etc/pam.d/system-local-login 中的本地登陆认证方法

    在第一行加上 auth sufficient pam_fprintd.so 表示优先使用指纹登陆

    sed -i  "/^$/aauth      sufficient pam_fprintd.so" /etc/pam.d/system-local-login
    
#%PAM-1.0

auth      sufficient pam_fprintd.so
auth      include   system-login
account   include   system-login
password  include   system-login
session   include   system-login
