Remember in January, when Hawaii residents received a terrifying text about an inbound ballistic missile with instructions to seek shelter immediately, but it turned out to be a false alarm?
Well, don't worry -- that's not going to happen with President Trump's new nationwide presidential alert texts ... it's a FEMA guarantee.
A spokesperson for the Homeland Security agency tells TMZ ... it has an infallible multi-step process in place to ensure the text system does not result in a major warning fail like what happened in Hawaii.
We're told for sending national alerts, the process begins with a special authentication procedure to make sure the person requesting to send it has the proper authority.
After verified approval, a 2-person "integrity check" procedure kicks in to ensure the alert contains the appropriate message and the info is properly formatted.
Finally, we're told the alert is only sent when BOTH of these alert operators have validated the content and format and hit the send button.
So, no -- POTUS can't just fire one off from his bed while watching cable news ... even if he tries.
