In a new system install (this has not happened to me before, and all my systems are Xubuntu 16.04 64bits, like this new one), both Chromium and Chrome at start throw a window to me asking something like this (translated on the fly from Spanish) "One application wants to access the passwords storage 'Default' but it is locked", it is asking about the keyring, I guess. I enter my user password and it complains that the password is not valid, this new window does not dissappear unless I click Cancel many times.
There are several questions even here in AskUbuntu about how to disable it (so do not flag this question for that, please). But as far as I know, if I disable it (keyring), the browsers will not be able anymore to save my web passwords in encrypted format.
So my question: how to fix this right? I don't just want to get rid of the message, I want to configure it right so both browsers will be able to store my websites passwords in a secure manner and don't prompt me about it anymore when I launch the browsers.
