Description

Overview

Versions before and including 11.25.1 are using dangerouslySetInnerHTML to display an informational message when used with a Passwordless or Enterprise connection.

  • For Passwordless connection, the value of the input (email or phone number) is displayed back to the user while waiting for verification code input.
