Error?
is steam client open?
Probably dont need parental code
see pinned discussions

Yes, my steam client is open, the error says the credential are not correct, try again, i don't know what i have to do. I see some discussions and i couldn't do it

Could be the problem due to some extensions that i have in google chrome?

I'd recommend using Firefox with quick cookie manager extension.

Then select "psteamcommunity.yuanyoumao.com" on the left
Select the Cookie with the value in the middle
From the Value box on the right, Right click + Select all, Right Click + Copy.

Make sure the domain on the left is just "psteamcommunity.yuanyoumao.com" not any other steam domain.
Make sure the cookies exactly match "sessionid" and "steamLoginSecure"

Checked still working for me.

Thank you man, i literally love you, you save me.

This works still but Chrome's cookie method that worked before doesn't after that family steam change on v1.10, it errors out with nothing in the parental part
