+- **SMTP is not configured:** If SMTP is not set up on your ThingsBoard instance, password recovery emails cannot be delivered. <DocLink product={props.product} path="user-guide/ui/mail-settings" useTbDocs>Make sure SMTP is configured correctly.</DocLink>
+- **Case sensitivity of email login:** By default, email login in ThingsBoard is case-sensitive for security reasons. To disable case sensitivity,

+parameter to **false** in your <DocLink product={props.product} path="reference/configuration/how-to-change-config" useTbDocs>configuration</DocLink> file. After that, you must restart your ThingsBoard service to apply the changes.
