    Got stuck after trying:
    Code:
    mv -v /var/cpanel/authn/twofactor_auth/tfa_userdata.json{,.bak}; echo ‘{}’ >> /var/cpanel/authn/twofactor_auth/tfa_userdata.json
    Now have a problem:
    Internal Server Error
    500
    Security Policy requires exec termination.

    Hello,

    Two-factor authentication should not prevent you from accessing the server via SSH as root. Once the server is booted out of rescue mode, you'd simply access the server via SSH as root and run those WHM API 1 commands.

    Thank you.

    Hello,

    It's unlikely that command will work while the server is booted in rescue mode, but it depends on the OS and the specific boot options you used. You may want to check with your hosting provider to see if they provide an option to disable the firewall rules so you can access the server via SSH.

    Thank you.

    You may find this third-party URL helpful:

    How to edit /etc/sysconfig/iptables from: RESCUE MODE boot?

    However, running an incorrect command could lead to data loss so it's generally advised to consult with a qualified system administrator or your hosting provider if you are not comfortable in rescue mode.

    Thank you.

    Solved by disabling CSF adding file csf.disable to csf folder.
    Code:
    touch /etc/csf/csf.disable
    After reboot managed to SSH login and disable 2FA with whmapi1
    Code:
    whmapi1 twofactorauth_disable_policy
