I noticed that I have passwords in the Password/Encryption Keys program . It appears that anybody who walked up to my computer could go look at all my passwords without needing a master password. Did I do something wrong or is this the default behavior? And if so, why?

and what if i lock my password is it get locked till i log out or for every time when i have 2to see password then i have to unlock keyrings . if then so how i protect my passwords from other . and why it is done so
