Is filing return through intermediery same as filing online?coz it seems easier way

a friend of mine just gave me a website(taxorigin.com), it gave me account and allowed me to upload 5 XMLs, and i did like the interface whereby i uploaded XMLs without use of logging on income tax web with username and password individually, and got the acknowledgement no in some minutes and PDF of ITR-V after some more minutes, only query of mine is that, are such uploads valid? i mean the upload is valid naa? once i get ITR-V, its same as filing on govt website na?
