Systems and methods for keyed communication tokens. A method may include receiving a key and a seed at a computing device, calculating a pseudo-random value based, at least in part, upon the seed, creating a concatenated string using the key and the pseudo-random value, hashing the concatenated string into a token, and adding the token to a user agent issued by a web browser as part of a command transmitted by the computing device. A computer system may be configured to identify a key and a seed, generate a pseudo-random value using the seed, create a concatenated string using the key and the pseudo-random value, hash the concatenated string into a token, and allow a web command in response to the web command including a user agent having the token or block the web command in response to the web command not including a user agent having the token.
