Authenticating Clients Using Tokens

A computing platform may receive, from a client communication server, a first token request requesting a token for a first client. The computing platform may generate a first token linked to a first record associated with the first client. Subsequently, the computing platform may send, to the client communication server, the first token linked to the first record associated with the first client. Thereafter, the computing platform may receive, from a client portal server, a first token validation request comprising the first token linked to the first record associated with the first client, and may validate the first token linked to the first record associated with the first client. Based on validating the first token, the computing platform may send, to the client portal server, a first token validation message directing the client portal server to provide the first record associated with the first client to the first client.
