SSH on Alamlinux still using password

[taker18]

Hello
it's my first time using Almalinx, and it shouldn't be different than Ubuntu
But maybe I am doing something wrong, which is most likely. let's see


1- I created a user for the desktop on local and remote server and another different one one for laptop
2- I created directory inside every user on the remote server

mkdir ~/.ssh && chmod 700 ~/.ssh

3- send the public key to remote server scp :

~/.ssh/id_rsa.pub desktop@IP :~/.ssh/authorized_keys

4- Edit the /etc/ssh/sshd_config
Find/edit/add ChallengeResponseAuthentication and set to no:

ChallengeResponseAuthentication no
Next, find PasswordAuthentication set to no too:

PasswordAuthentication no
Search for UsePAM and set to no, too:

UsePAM no
Finally look for PermitRootLogin and set it to no too:
PermitRootLogin no
---> Finally restart SSH with

sudo systemctl restart sshd

After all of this, it used to work with Ubuntu nice and sweet
but I am still able to ssh with the password
for example, I can ssh from anywhere to any user with a password still.
I want to cancel the password login. well, indeed, I am able to cancel the root login but not the password.

any help here

I found the Solution: my Solution was adding this command at sudo nano /etc/ssh/sshd_config

Match User mysuer
PasswordAuthentication no

the password is disabled, indeed

Yes but only for that user if I'm not mistaken.

Yes but only for that user if I'm not mistaken.

Yes, you are correct. That was my issue. I was not able to disable the user password login. now, only SSH with the public key is allowed. I was successful in disabling the root password, no issue; the issue was only with the user.

 

[Richard G]

No I mean probably the password is only disabled for that user, probably not disabled for other users.
