# Retrieve authentication settings

`GET https://api.cademi.com.br/api/v3/settings/authentication`

Operation ID: `settings.authentication.get` · API v3

Returns the authentication settings of the account: password rules, reCAPTCHA, two-factor authentication for administrators, Google sign-in, the device limit, and the layout of the access screens.

Secrets are never returned; the `configured` fields indicate whether they have been set.

The response includes an `ETag` representing the current revision. Send this value in the `If-Match` header when updating these settings to avoid overwriting a newer version.

Required permissions: `settings.read`.
