      "value": "The Bastion provides authentication, authorization, traceability and auditability for SSH accesses. SCP and SFTP plugins don't honor group-based JIT MFA. Establishing a SCP/SFTP connection through The Bastion via a group access where MFA is enforced does not ask for additional factor. This abnormal behavior only applies to per-group-based JIT MFA. Other MFA setup types, such as Immediate MFA, JIT MFA on a per-plugin basis and JIT MFA on a per-account basis are not affected. This issue has been patched in version 3.14.15."

Establecer una conexi\u00f3n SCP/SFTP a trav\u00e9s de The Bastion por medio de un acceso grupal donde se aplica MFA no requiere ning\u00fan factor adicional. Este comportamiento anormal solo se aplica a JIT MFA por grupo. Otros tipos de configuraci\u00f3n de MFA, como Immediate MFA, JIT MFA por complemento y JIT MFA por cuenta, no se ven afectados. Este problema se solucion\u00f3 en la versi\u00f3n 3.14.15."
