Hey, today I'm showing to you guys how to fully secure any kind of YouTube easely.
1st step - We are going to change the Google account linked to the desired YouTube channel, making the channel not able to recover by recovering the old Google account. You can do that by clic'ing here.
2nd step - When the channel is linked to the fresh Google account and @gmail.com email, we have to secure it. Don't forget to use a 100% secure recovery email and using a strong password. Then, by enabling 2-steps-verification, the account'd be enough secured.
3rd and last step - If you did all correctly, your channel is linked to a new and secure Google account = channel fully secured.
