Where Are Passwords Saved on Ubuntu?

Ubuntu 17

In the world of Ubuntu, a popular Linux-based operating system, managing and understanding where passwords are stored can be a crucial part of system administration. This article will delve into the different locations where Ubuntu stores passwords and how you can access them.

Quick Answer

Passwords in Ubuntu are stored in different locations depending on the type of password. System account passwords are stored in the /etc/shadow file, network passwords are stored in the /etc/NetworkManager/system-connections directory, and passwords stored in the Gnome Keyring are located in the ~/.gnome2/keyrings directory.

System Account Passwords

The passwords for system accounts in Ubuntu are stored in a file named /etc/shadow. This file is not accessible by regular users due to its sensitive nature and can only be read by users with root privileges.

The passwords in the /etc/shadow file are not stored in plaintext. Instead, they are hashed using SHA encryption, making them unreadable.

To view the contents of the /etc/shadow file, you can use the cat command with sudo:

sudo cat /etc/shadow

In this command, sudo is used to run the command with root privileges, cat is a utility that reads files sequentially, writing them to standard output, and /etc/shadow is the file you want to read.

Network Passwords

Network or WiFi passwords in Ubuntu are stored in the /etc/NetworkManager/system-connections directory. Each network connection has its own file with its configuration, including the password.

To access these files, you need root privileges. The passwords in these files are not encrypted.

Here’s how you can list all the connection files:

sudo ls /etc/NetworkManager/system-connections

In this command, sudo is used to run the command with root privileges, ls lists the contents of a directory, and /etc/NetworkManager/system-connections is the directory you want to list.

Gnome Keyring

Gnome’s password manager, known as the Gnome Keyring, stores its passwords in the ~/.gnome2/keyrings directory. These files are not human-readable and should be accessed using Seahorse, Gnome’s default password manager.

In older Ubuntu systems, WiFi passwords were also stored in the Gnome Keyring.

To access the Gnome Keyring, you can open Seahorse:

seahorse

In this command, seahorse is the name of the application you want to run.

Conclusion

Understanding where passwords are stored in Ubuntu can help you manage your system more effectively. Whether you’re dealing with system account passwords, network passwords, or passwords stored in the Gnome Keyring, knowing where these passwords are stored and how to access them is crucial.

Remember to handle this information responsibly, as mishandling passwords can lead to serious security issues. Always use root privileges judiciously and ensure your system is secure.
