5. A system for establishing credentials for securing text message communications, the system comprising: a processor, and a memory, the memory including code representing instructions that when executed cause the processor to: receive, from a device, a first text message, the first text message being directed to a service number, wherein the first text message includes a user number and a request to establish a secure credential for communicating with a text messaging application; transmit, to the device, an initiation message including a first user-specific system number to which the device is to direct future text messages; receive a second text message that includes the user number; determine that the second text message is not authentic in response to determining the second text message is not directed to the first user-specific system number; and transmit, to the device, a notification message that includes a second user-specific system number to which the device is to direct future text messages in response to determining that the second text message is not authentic, the second user-specific system number being different from the first user-specific system number.
