What is Keyring?
The keyring will store the password and the encrypted key, such as a storage place for the password. Every user on your Linux system will have their keyring that is the same as the password used to log into the desktop. Your password will be encrypted, and when you open the application, for example, the Google Chrome browser, the keyring will enter the password for you.
But the problem arises if you activate the automatic login feature, in this case, you are logged into your Linux system without entering the password, so then keyring will not enter the password for you every time you open a certain application.
This is actually one of the security features, that's the reason why every time you open a particular application, a popup will appear asking you to enter the password.
