More information
As stated in the documentation, this action function has protections that offer some safety but are not designed to prevent all types of abuse. Depending on the sensitivity of private data in your DataStore and the likelihood of abuse of your site, you may choose to disable this action function or restrict its use with a IAuthFunctions plugin.
