Methods and systems of facilitating authentication for accessing a service

A method of facilitating authentication for accessing a service, the method comprises:

• receiving, using a communication device, a first API call from a user device, wherein the first API call is associated with accessing the service, wherein the first API call comprises a first key;
• receiving, using a communication device, an authentication data from an external server based on the first API call;
• analyzing, using a sidecar module, the first key and the authentication data;
• determining, using the sidecar module, a key validity based data on the analyzing, wherein the key validity data indicates one of a validity of the first key and an invalidity of the first key;
• generating, using the sidecar module, a first process session key based on the key validity data indicating the validity of the first key, wherein the first process session key facilitates verification of a first data received by the user device;
• transmitting, using the communication device, the first process session key to the user device;
• generating, using the sidecar module, a first response based on the key validity data indicating the validity of the first key, wherein the first response comprises a first token;
• transmitting, using the communication device, the first response to a user device sidecar, wherein the first response comprises the first process session key, wherein the user device is configured to verify an authenticity of the first response based on the first process session key comprised in the first response;
• receiving, using the communication device, a second API call, wherein the second API call comprises the first token;
• analyzing, using the sidecar module, the first token;
• determining, using the sidecar module, a token validity based on the analyzing, wherein the token validity comprises one of a validity of the first token and an invalidity of the first token;
• generating, using the sidecar module, a second process session key based on the token validity indicating the validity of the first token, wherein the second process session key facilitates verification of a second data received by the user device;
• transmitting, using the communication device, the second process session key to the user device;
• generating, using the sidecar module, a second response based on the token validity indicating the validity of the first token, wherein the second response comprises the second process session key;
• transmitting, using the communication device, the second response to the user device, wherein the user device is configured to verify an authenticity of the second response based on the second process session key comprised in the second response.

A system for facilitating authentication for accessing a service, the system comprises:

• a communication device configured to:
• receive a first API call from a user device, wherein the first API call is associated with accessing the service, wherein the first API call comprises a first key;
• transmit a first process session key to the user device;
• transmit a first response to a user device sidecar, wherein the first response comprises the first process session key, wherein the user device is configured to verify an authenticity of the first response based on the first process session key comprised in the first response;
• receive a second API call, wherein the second API call comprises the first token;
• transmit a second process session key to the user device;
• transmit a second response to the user device sidecar, wherein the user device is configured to verify an authenticity of the second response based on the second process session key comprised in the second response, wherein the second response;
• and
• a sidecar module communicatively coupled with the communication device, wherein the sidecar module is configured to:
• analyze the first key;
• determine a key validity based data on the analyzing, wherein the key validity data indicates one of a validity of the first key and an invalidity of the first key;
• generate the first process session key based on the key validity data indicating the validity of the first key;
• generate the first response based on the key validity data indicating the validity of the first key, wherein the first response comprises a first token;
• analyze the first token;
• determine a token validity based on the analyzing, wherein the token validity indicates one of a validity of the first token and an invalidity of the first token;
• generate the second process session key based on the token validity indicating the validity of the first token;
• and
• generate the second response based on the token validity indicating the validity of the first token, wherein the second response comprises the second process session key.
