Yes you can remove your password from popup authentication, as well as remove passwords in general or your keyring. I would not recommend any of this as it is a security risk however if you wish you can follow the following after typing
If you don’t want to be prompted for any password while running sudo then we can use the NOPASSWD parameter on a particular entry:
admin ALL = NOPASSWD: ALL
this parameter is the opposite of the default PASSWD and will no longer require any password for the user “admin” while running 'sudo'. This can be of useful while running scripts that will launch 'sudo' (in this case I would recommend to enable NOPASSWD only for the needed commands), or just if you don’t want to keep typing the password. Obviously with this commodity, you will reduce the security of sudo: if someone hacks the “admin” account then this can be easily used to gain root privileges.
Another option that can be used to control the prompt for a password is the global flag: authenticate. This is by default ON and this means that it will ask the user to authenticate with a password. This can be overwritten as seen above with the 'NOPASSWD' on a particular entry. If we want to disable it globally, this can be done with:
Once set, this will disable authentication for all users that use the defaults like our “admin” sample from above. It can be overwritten on particular definition by setting the 'PASSWD' parameter:
admin ALL=(ALL) PASSWD: ALL
Note: this post doesn’t recommend you to disable the passwords usage in sudo (this is not a good idea, by the way), but just to show you what options are available and how you can use them. Knowing the security implications of disabling password usage in sudo, use them wisely based on your particular needs.
