Q: I cant remember my password for my other mail account.. How do I assess or reset it..  Mail keeps asking for password

You would need to contact Cogeco. https://www.cogeco.ca/web/on/en/residential/support/contact_phone.php

I'm not familiar with that mail account. But if you use it thru the mail app on your computer, you can open keychain access.Click login under keychains and double click the mail account in question.  Check the box to show password. A window will open to type you admin password and then click allow and it will show the mail password for that account. If this is an account thru a browser that will not work.
