Remove Password Prompt For sudo
|
|
If you disable the sudo password for your account, you will seriously compromise the security of your computer. Anyone sitting at your unattended, logged in account will have complete Root access, and remote exploits become much easier for malicious crackers. |

This method is NOT suggested nor supported by the designers of Ubuntu.
- Please do not suggest this to others unless you personally are available 24/7 to support the user if they have issues as a result of running a shell as Root.
These instructions are to remove the prompt for a password when using the sudo command. The sudo command will still need to be used for Root access though.
Edit the sudoers file
Open a Terminal window. Type in sudo visudo.Add the following line to the END of the file (if not at the end it can be nullified by later entries):
<username> ALL=NOPASSWD: ALL
Replace <username> with your user name (without the <>). This is assuming that Ubuntu has created a group with the same name as your user name, which is typical. You can alternately use the group users or any other such group you are in. Just make sure you are in that group. This can be checked by going to System->Administration->Users and Groups
Example:
michael ALL=NOPASSWD: ALL
Type in ^x to exit. This should prompt for an option to save the file, type in Y to save.
Log out, and then log back in. This should now allow you to run the sudo command without being prompted for a password.
Or to do this for the system wide group sudo
root$ echo "%sudo ALL=(ALL) NOPASSWD: ALL" >> /etc/sudoers
Log out, and then back in.
