screen -r
You don’t have to enter the session ID if you only have one instance of Screen. You must specify which session ID you want to reconnect to if you have more than one.
With the command screen -ls, you may view the list of session IDs. Each screen session has a unique ID.
Add the ID to the screen -r command once you have it.
screen -r sessionID

screen -r 3361.upgrade

password your_password
Change your password for a reliable password of your choosing. The next time you attempt to reconnect to the password-protected screen, you will need to provide two passwords: your Screen password and your Linux password.
Changing Screen
The screen makes use of a programmable configuration file, like many other Linux programs. The system configuration file is located at /etc/screenrc. /.screenrc contains the user’s configuration file.
