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?
