Thanks for the response,
I understand the function of the keyring.
The exact message is:
Blockquote Enter password to unlock
An application wants access to the keyring “Default keyring”, but it is locked
This message is not asking for a new initial password but what appears to be a password already created.
I have spent hours trying all kinds of password including the L5 pin so the keyring password cannot possibly be that.
Thanks for the information about Seahorse. I did read those threads when I was looking for a possible solution.
