The answers above are correct, I just want to give another option that may suits you better.
- A brand new raspberry pi
- You want to change the default username
- You want to adapt also the main group from
- You want other things to work out like sudo and auto-login
Step 1: stop user
pi from running before the change.
Step 2: make the user change
- If you see the graphical login prompt, you are good. Do not login. Instead, press ALT+F1 (* if you want to do it via ssh, see the apendix)
- After ALT+F1, you should see a
login question (and not an autologin).
- Login as
root with your root password. Now you are alone in the system, and changes to
pi will not be met with
usermod: user pi is currently used by process 2104. Check with
ps -u pi to see an empty list.
- Very carefully, key by key, type
usermod -l mypie pi . This will change your username, from
/etc/passwd file, but things are not ready yet. Anyway, check with
tail /etc/passwd and see the last line
mypie:1000:... The 1000 is the UID and it is now yours.
su mypie just to be sure. Do nothing. Just
exit again to root. It should work. Now you need to adjust the group and a
Step 3: make the group change
- Type, again carefully,
groupmod -n mypie pi . This will change the
pi group name. Check it with
tail /etc/group and you will see the last line the new name associated with
- Just to clarify, type
ls -la /home/pi and you will see that the
pi HOME now belongs to you,
Step 4: lets adopt the new home.
- I see in the answers above the creation of a new folder, copying everything. No need. Lets just use the same.
- First move to
cd /home to make it easier. Type
ls -la and see
- Type carefully:
mv pi mypie . You now need to associate this change with your new user.
- Type carefully:
usermod -d /home/mypie mypie . This will change your home directory. Check it with
tail /etc/passwd and look at the sixth field (separated by
Step 5: some adjusts after the fact.
Change your password
- Reboot with
- Login as your new user
mypie in the graphical interface.
- Open a terminal.
auto-login again if you will (I don't recommend, but well)
passwd to change the password of
mypie to something else than
sudo su - and you will be asked your password.
Make your sudo passwordless again (I don't recommend as well)
- If you want to autologin your new account, edit the file:
- find the line with
#autologin-user=, change it to
autologin-user=mypie (no comment #)
- If you want back the ALT+F1 autologin, find and edit the file:
$vim /etc/systemd/system/[email protected] and change the line
#ExecStart=-/sbin/agetty --autologin mypie --noclear %I $TERM
While you are into it, change your hostname
- Move yourself (root) to
- Rename the file
- Open it
vim 010_mypie_nopasswd and change the line
pi ALL=(ALL) NOPASSWD: ALL to, obviously
mypie ALL=(ALL) NOPASSWD: ALL. It is read-only, so save it forcing with
$vim /etc/hosts and change
127.0.1.1 raspberry to something more appropriate like
$vim /etc/hostname and let a single line with
Step 6: reboot
Appendix - ssh
- You may want to do this via ssh. For this to work, first you need to allow root login.
- Find the file
- Comment the line
- Add the line
- Save, exit, restart ssh with
- After you have done it, undo this changes as they are too dangerous to let that way.
- Same file, delete
PermitRootLogin yes line and remove the comment from
Note 1: This is a guide, and the content deals with very dangerous commands. Backup first, or be aware that maybe you will need to burn again your image. As I am assuming a brand new raspberry pi, there is not much to backup anyway. But if you adapt it to another situation, be advised.
Note 2: There might be more things to change. As I am new to the Raspberry pi (I got mine 2 days ago), I may find other adjusts I left out and I will edit this answer again.
Note 3: My first attempt was to move
pi user and
pi group to another
GID (1001) and create a new user for me as
1000. That didn't quite go as I planned and I needed to burn my SD card again after spending the whole day trying to figure out why the "configure you pi" program would not work anymore. But well, this way here is far easier anyway, so here you go: a new pi with just your username as UID 1000 (and all the good stuff in your home).
Note 4: Be advised, after doing that, the standard configuration tool stops working.
