# No se pudo obtener el token de acceso

## Problema

Cuando intentas iniciar sesión en KONNEKT, aparece el mensaje de error "Failed to obtain access token".

## Causa

KONNEKT no admite tener "Excluded Apps" en una directiva de Conditional Access de Microsoft Entra (Azure AD) que requiera MFA en combinación con una sesión de Windows sin SSO.

## Solución alternativa

Nuestra solución alternativa recomendada es habilitar la máquina Windows para que tenga un Primary Refresh Token (PRT), por ejemplo mediante Entra Join (AAD Join) o Register. Consulta [aquí ](https://learn.microsoft.com/en-us/entra/identity/devices/concept-primary-refresh-token#how-is-a-prt-issued)para más detalles.

Otras alternativas son (no realmente recomendadas):

* Eliminar el requisito de MFA de la correspondiente directiva de Conditional Access. Para mantener cierta seguridad en las directivas de CA sin MFA, podrías imponer [Trusted Locations (por ejemplo, direcciones IP públicas de tus hosts VDI)](https://learn.microsoft.com/en-us/entra/identity/conditional-access/location-condition)

o

* usar una directiva de Conditional Access sin "Excluded Apps". Consulta también [configuración de Conditional Access](/es/installation/security/conditional-access.md).

## Solución

Se implementó una solución en la versión 2.10 de KONNEKT - "[Enhanced OAuth](/es/configuration/system-settings/autenticacion-mejorada.md)".

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.konnekt.io/es/troubleshooting/access-token-issues/failed-to-obtain-access-token.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
