Why Does My Login Fail After I Enable 2FA?

The login failed probably because file configurations or the login mode was incorrect.

Correcting File Configurations

Check whether the configuration file is correct.

Configuration file path: /etc/ssh/sshd_config

Configuration items:

PermitEmptyPasswords no

UsePAM yes

ChallengeResponseAuthentication yes

If you use the root account for login,the following configuration item is required:

PermitRootLogin yes

Correcting the Login Mode

If you attempted to log in in either of the following ways, your login would fail.

  • Used CloudShell to log in to an ECS.
  • Attempted to log in to a Linux server through a CBH instance.

Failure cause: 2FA is implemented through a built-in module, which cannot be displayed if you log in in the preceding ways. As a result, the login authentication fails.

Solution: Perform login authentication by referring to How Do I Use 2FA?
