How to login using ssh without any sort of authentication?

Question

I have seen similar questions, but nothing helped.

Like here:

• SSH login with no authentication
• SSH session without ANY authentication

Answer 1

You should look at setting PermitEmptyPasswords to yes in your sshd_config file and restard sshd service.

PermitEmptyPasswords When password authentication is allowed, it specifies whether the server allows login to accounts with empty password strings. The default is ''no''.
