Don’t use your usual password, as the method used is pretty weak (standard DES)

Open a screen session :

$ screen

Inside the session press ctrl + a then type :password

If successfully set, you should see [ Password moved into copybuffer ] in the lower left corner of the terminal.

Now you can detach by pressing ctrl + a then d

Reattach with :

$ screen -r

And now you should be prompted for the session password.
