A security hole in Gnome allows anyone to see your keyring passwords without needing to enter so much as a password.
Despite needing to enter your root password to alter such basic things as CPU Scaling, you are not once prompted to enter it to access the Passwords and Encryption Keyring.
Ubuntu Forum user humphreybc, who first reported this anomaly on the Ubuntu Forums, posted a quick –step-through guide so you can see for yourself how dodgy this lapse is: -
1. Restart your computer and login. Do not enter any passwords after your desktop has loaded.
2. Go to Applications > Accessories > Passwords and Encryption Keyrings
3. Click on the 'Login' folder to drop down and view the programs that store data here.
4. Double click on something you want to look at.
5. Click Password to show some dots, then uncheck the box below the dots marked "Show password"
Rest Here
