I was recently notified of a data breach involving my Yahoo! mail account. I looked it up and sure enough, my problem for the hackers is the password had long been changed. But I did a search to see if I had any remaining accounts using the password and found my amateur radio call sign @n2xu Twitter account long ago had the same password… I had changed the email for the Twitter account sometime in 2016 but never verified it so the email address change didn’t take. I had Twitter send a password reset and I got it at the old Yahoo address. Success! Up to this point I’d thought I lost the password.
