Hi!

This is covered in the website hacking course, amongst other cool web attacks. But here is an article you can read: https://infinitelogins.com/2020/02/22/how-to-brute-force-websites-using-hydra/

In any case this won’t work to revocer your gmail password, google servers are well protected against this kind of attacks and you will end up blocking your account or getting your ip banned for a time, so I won’t suggest to try it. Instead use the recover password methods offered by gmail.

Greetings!
Diego
