Pulling my hair out… I was forced to create a “secure mail key” in order to send email to an existing email account I had added in Thunderbird. (I am going to migrate away from Postbox.)
I need to understand something (the AT&T support rep couldn’t tell me): does this secure mail key replace my original login password? what is their relationship to each other?
Honestly, I don’t understand how a password made up of all lowercase letters with no numbers or special characters could be more secure than the password I was using. So that makes me wonder if it is functioning as an additional password.
The account in question was setup in Thunderbird with my own password, and had already successfully received messages without the secure mail key at the time. This key apparently was necessary to send messages. I had to go to att.com and log in under this account to create it. Then when Thunderbird gave me the alert that the server needed a new password, I pasted the new “secure mail key” string in the dialog and saved it. The message sent successfully.
So: did I replace my earlier password? that password was still required to log into the web browser at att.com to deal with email or account settings there.
Can someone please explain what the relationship is between the secure mail key I created and the password I already had? and is it really secure if it is made up of just lowercase letters?
