Some time ago I set up another email address (BT internet, POP3 & SMTP both mail.btinternet.com exactly the same as another emmail address I use). Unfortunately, I've forgotten the password - I can't believe it's the only thing I've never entered into my password manager.
Is there any way of getting at it? I've tried putting the name into Yahoo mail 'Forgotten your password, you idiot?' screen together with my date of birth, but it says it can't find me. I've happily been using it to send emails this morning but now I want to retrieve something from webmail - and can't.
