No Tails, uma senha de administração é necessária para realizar tarefas de administração de sistema.
Por exemplo:

• Para instalar novos programas e pacotes
• Para acessar os discos rígidos internos do computador
• Para execuar comandos com sudo

By default, the administration password is disabled for better security. This can prevent an attacker with physical or remote access to your Tails system to gain administration privileges and perform administration tasks against your will.

Set up an administration password

In order to perform administration tasks, you need to set up an administration password when starting Tails, using Tails Greeter.

1. When Tails Greeter appears, in the Welcome to Tails window, click on the Yes button. Then click on the Forward button.

2. In the Administration password section, specify a password of your choice in both the Password and Verify Password text boxes.
