Vagrant - Changing the ssh connection password with the machine

Question

Well people, I’m doing some tests with virtual machines made with Vagrant, but now, I’m having a problem that is to change the default password connection with the virtual machine(Default password: "Vagrant").

Below is the Vagrantfile:

Vagrant.configure(2) do |config|
  config.vm.box = "192.168.0.21"
  config.ssh.username = "vagrant"
  config.ssh.password = '123'
  config.ssh.insert_key = true
  config.vm.network "public_network", bridge: "wlan0", ip: "192.168.0.21" 
  config.vm.provider "virtualbox" do |v|
    v.name = "192.168.0.21"
    v.cpus = 1
    v.memory = 512
  end
end

Note that I changed the password by config.ssh.password, but when I try to connect by ssh through the terminal, the password remains the default "Vagrant".

When I change the username (config.ssh.username) to "root", for example, it gives this problem :

According to the documentation for Vagrantfile, the value of the key config.ssh.password is used when logging into the virtual machine via SSH and not to set the password itself. The password is set in the image (box box) that you are using. The same explanation goes for the key config.ssh.username.

In case you wanted to modify the password of your virtual machine you can first login normally in the VM and only then change the password:

$ vagrant ssh
$ passwd
Changing password for vagrant.
Old Password:
New Password:
Confirm New Password:

After this step change the config.ssh.password for the password you just set within the VM.
