keychain access

Hi there,

the following issue occurs with email account access information registered with key chain:

I have two distinct yahoo email accounts but key chain has apparently only registered the account access information of one. For the other one (the older one), I am not even prompted whether or not my access information ought to be saved or not. How can I fix this issue so that I am prompted to save the access information in question with key chain?

Best wishes and happy holidays to all of you!

Frank
