Recently I came across this word in a basic authentication article. What it meant by base64 clear text usrname and password on the network?
Thanks
It means encoding the username and password using base 64. The result won't look too much like your username and password but it's pretty easy to reverse the operation to get the plain text.

For example the string password
encoded in base 64 is cGFzc3dvcmQ=
