# AuthenticationResponse

The details of the authentication response.

## Properties

- success: (\`boolean\`) Whether the authentication was successful.
- authIdentity: (\[AuthIdentityDTO]\(../../../auth/interfaces/auth.AuthIdentityDTO/page.mdx)) The authenticated user's details.

  - id: (\`string\`) The ID of the auth identity.

  - provider\_identities: (\[ProviderIdentityDTO]\(../../../auth/interfaces/auth.ProviderIdentityDTO/page.mdx)\[]) The list of provider identities linked to the auth identity.

    - id: (\`string\`) The ID of the provider identity.

    - provider: (\`string\`)

    - entity\_id: (\`string\`) The user's identifier. For example, when using the \`emailpass\`
      provider, the \`entity\_id\` would be the user's email.

    - auth\_identity\_id: (\`string\`) The ID of the auth identity linked to the provider identity.

    - auth\_identity: (\[AuthIdentityDTO]\(../../../auth/interfaces/auth.AuthIdentityDTO/page.mdx)) The auth identity linked to the provider identity.

    - provider\_metadata: (\`Record\<string, unknown>\`) Holds custom data related to the provider in key-value pairs.

    - user\_metadata: (\`Record\<string, unknown>\`) Holds custom data related to the user in key-value pairs.

  - app\_metadata: (\`Record\<string, unknown>\`) Holds information related to the actor IDs tied to the auth identity.
- error: (\`string\`) If an error occurs during the authentication process,
  whether within the Auth Module or a third-party provider,
  the error message is set in this field.
- location: (\`string\`) The URL to redirect to for further authentication action
  with a third-party provider. This takes precedence before
  the \`success\` field.

  So, after checking that authentication is successful,
  you should check whether this field is defined and, if so, redirect to the
  specified location.
