Selenium + authentication-proxies

Hello, I am trying to use selenium with proxies that need authentication.
For that I have to use an extension. Now my question is, how do I get the proxy username and password?

Is there a variable for that?

Thanks in advance!

Hello @R4YVEN
Normally the username and password are in the line of the proxy itself for example with luminati proxies it’s like that :

zproxy.lum-superproxy.io:(PORT):lum-customer-<USERNAME>-zone-<zone number>ip-(IP):<PASSWORD>

Otherwise you can try to look in the dashboard of the site from which you bought the proxies it will surely be informed
