指纹认证不仅用于登录

Question

我使用的是 18.04 版本，已成功启用指纹登录。我不仅想使用指纹登录，如果可能的话，还想使用指纹登录：

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

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
