# Authentication flows skip reCaptcha even when the option is enabled

Due to an incomplete implementation, reCaptcha is not applied to certain authentication flows even when the reCaptcha option is enabled. An attacker can bypass the protection and run brute force attacks that may lead to unauthorized access to user accounts and sensitive information.

_Summary, check and fix written by a model from the sources; labelled as such._

## From the sources

Due to an incomplete implementation, reCaptcha is not applied to certain authentication flows even when the reCaptcha option is enabled. This oversight permits attackers to bypass the intended protection mechanism.

Brute force attacks, if successful, can lead to unauthorized access to user accounts and sensitive information by systematically attempting various credential combinations.
