Gnu Screen asks for password when I close a screen: what password does it want?

Question

I have multiple screens running the same long process.

When I try to close one (C-a, x), I get a blank screen with:

Key:    •

When I type anything and press return, I get:

Again:  •

If it's different, I get "Passwords don't match" and if it's the same I get:

Screen used by Andrew Swift <local>.
Password:•

My administrator password doesn't work.

How can I close the screen correctly?

Answer 1

The CTRL-A x - mean "lock the screen".

So, it asking you for the locking password (of course twice). You can enter any string. Of course, when they did't matches it says mischmah.

After you locked the screen session, you need enter the password again for unlock the session. Simply enter the chosed password again.

Instead of locking, you can "detach the screen" session (CTRL-A D) or you simply use CTRL-D for ending the running shell..
