What did U mean is that we just need to use the password of linux account to reattach a detached screen seesion? but now my password of linux user account is prompt not correct.Now I can't reattach a detached session.

I think you are looking at old documentation.

It now apparently always uses PAM to authenticate the account.

I just don't understood why here password none is config, we need to enter the password also. what does this "Same as not even mentioning it." words standing for

Dear screen maintainers & devs,

Thanks for maintaining GNU screen!

From ChatGPT I learnt, that in "GNU Screen 4.99 (or current dev branch), the ability to disable passwords was removed, and there is no straightforward configuration option to achieve this. Password authentication is now enforced by default in GNU Screen 4.99 and later versions."

I couldn't figure out a way using the docs to disable GNU screen's password prompt when re-attaching a detached session.

My issue and my temporary workaround is described here:
https://marcgloor.github.io/gnuscreenpatch.html

Can you confirm that the ability to disable passwords was intentionally removed? If so, I would request this option to be re-added to the program logic again.

Thanks
Marc
