How to Fix "Login Without a Password is Forbidden by Configuration" Error

In Unix-like operating systems, the "login without a password is forbidden by configuration" error message often appears when you try to log in to a system using the ssh command and you do not specify a password. This error message indicates that the system is configured to not allow login without a password, which is a security measure to prevent unauthorized access to the system.

To fix this error, you will need to specify a password when logging in to the system. If you do not know the password, you will need to contact the system administrator or someone with access to the password in order to log in.

If you are the system administrator and you want to change the configuration so that login without a password is allowed, you can do so by modifying the AllowNoPassword option in the sshd_config file. This file is typically located in the /etc/ssh directory on most systems.

To allow login without a password, you will need to set the AllowNoPassword option to yes . For example:

Once you have made this change, you will need to restart the ssh daemon in order for the change to take effect. On most systems, you can do this by running the following command:

Alternatively, you can also use the service command to restart the ssh daemon:

After making these changes, you should be able to log in to the system without specifying a password. However, it is generally not recommended to allow login without a password, as it reduces the security of the system. Instead, you may want to consider using public key authentication or two-factor authentication to secure your system.
