 #### Speed of data transfer
 
-Some users may have the question why the time for sending/receiving data with this library was increased when using the different authentication methods which someone compare with other libraries and platforms.
+This library focuses on the user privacy and user data protection which follows Google authentication processes. Setting the security rules to allow public access read and write, is not recommended even the data transmision time in this case was significantly reduced as it does not require any auth token then the overall data size was reduced, but anyone can steal, modify, or delete data in your database.
 
 
-Once the token is ready for authentication, the data transmission time will depend on the time used in SSL/TLS handshake process (only for new session opening), the size of http header (included auth token size) and payload to be transmitted and the SSL client buffer reserved size especially in ESP8266.
+Some users may have the question why the time for sending/receiving data with this library was increased when using the different authentication methods which someone compares this with other libraries and platforms which some claims to be fast or has low latency in operation as it does not use any auth token and always requires public read/write allowance security rules which is not good for your privacy and data.

 The legacy token size is relatively small, only 40 bytes, result in smallest header to send, while the size of id token generated using Email/Password is quite large, approx. 900 bytes. result in larger header to send.
