指纹认证不仅用于登录

Question

我在 18.04 并已成功启用指纹登录。我想不仅使用我的指纹登录，而且如果可能的话还可以：

1. 当我执行sudo命令时在终端中进行身份验证
2. 在 Gnome 中进行身份验证（即安装应用程序等时）
3. 解锁钥匙圈物品（这是我能找到的唯一信息，显然这是不可能的）

的输出grep print /etc/pam.d -R：

/etc/pam.d/gdm-fingerprint:auth required    pam_fprintd.so
/etc/pam.d/gdm-fingerprint:password required       pam_fprintd.so
