====== Tinycore Passwords ======

If you want to prevent other people from logging into your computer, you can add passwords to Tinycore.

If you are using the Extlinux bootloader, another option is to add passwords to Extlinux. For more information, 
see [[extlinux_passwd|Extlinux Passwords]].

==== Add Passwords to Tinycore ====

To add a password for user tc, open the terminal and type

<code>passwd</code>

To add a password for root, type

<code>sudo passwd</code>

The procedure described above stores the password using 8-byte parity, so the password will be 8 characters long, i.e. "passwd 123456789" will allow to login using "12345678" or "12345678blahblah" as password. This occurs on 4.1 and 4.2.
Use "passwd -a md5" instead.

==== Save Passwords using Backup ====

If you use Backup, to save passwords, add

<code>etc/shadow</code>

to /opt/.filetool.lst

Backup when shutting down the computer.

==== Save Passwords using Persistent opt ====

If you use persistent opt, open the terminal and type

<code>sudo cp /etc/shadow /opt/shadow</code>

Add the following to /opt/bootsync.sh

<code>sudo mv /etc/shadow /etc/shadow_old
sudo cp /opt/shadow /etc/shadow</code>

Note that this will apply group staff and mode g+w to /opt/shadow on each boot, as it's the case with every file in /opt.

==== Use Password to Log In ====

To be prompted for Username and Password when logging in, add the bootcode

<code>noautologin</code>

to the bootloader.

==== Don't Log In as Root ====

Log in as tc, not as root.

If you want to perform root tasks, use sudo before commands.

==== bootsync.sh and bootlocal.sh ====

If you want commands executed every time you start the computer, add them to /opt/bootsync.sh or /opt/bootlocal.sh.

/opt/bootsync.sh is run early in the boot process.

/opt/bootlocal.sh is run later in the boot process.

Most commands should go in /opt/bootlocal.sh, except commands you want executed early in the boot process.
