SMS is commonly used for services to communicate one-time passwords or two-factor authentication codes . With Pulse SMS, when you receive one of these codes, one of the buttons on the notification will allow you to quickly copy that code without needing to go into the app and do it manually. Copying the code will also mark the convrsation as read and dismiss the notification.
This feature is currently only available in English. The password matching depends on a complex set of rules, which cannot be translated directly into other languages.
