Good afternoon. I don't fully understand you, what you want to do and what you want to achieve.
Look in the direction of getting and changing the Get request parameter in the address bar.
using multiple accounts on the same site, i have to get 1 fingerprint for each account and save it in order to reload each account with its own fingerprint right?
yes
each fingerprint request on server give a new one different from the last request?
Almost always will be new.
as free member is there any limit on fingerprint request ?
