Verifying an identity of a message sender

One or more non-transient computer readable media comprising computer-executable instructions, wherein when the computer-executable instructions are executed by one or more processors, the one or more processors are configured to:

• receive registration information associated with a user from a first device;
• receive a first message from a client over a network;
• verify that the first message is from the user based on the registration information;
• in response to verifying that the first message is from the user:
• generate a first credential based on data associated with the first message,
• route the first message toward a remote device, and
• store the first credential;
• receive a second message from the remote device requesting that a second credential be verified;
• determine whether the second credential is valid based on the first credential in response to the second message;
• and
• send a notification to the remote device indicating whether the second credential is valid.

A method comprising:

• receiving registration information of a user from a first device, wherein the registration information includes a first user identifier and a first password;
• receiving a first message, a second user identifier, and a second password from a client over a network;
• verifying that the first message is from the user based on the first user identifier, the first password, the second user identifier, and the second password;
• generate a first hash based on the first message in response to successfully verifying that the first message is from the user;
• storing the first hash;
• routing the first message toward a remote device,
• receiving a second message from the remote device requesting that a second hash be validated;
• determining whether the second hash is valid based on the first hash;
• and
• sending a notification to the remote device indicating whether the second hash is valid.
