I have access to the original email when I signed up with lastpass. I do not have access to the security email since that domain has been shutdown. When I try to login, verification is being sent to the security email. There is no concern anyone has access to my original email. 2FA is setup on my account so I don't understand why I'm not given that option to login. I do remember my master password and it's 10+ characters long with complexity.
I got 100% the same problem here and I'm stuck (no paid subscription, no support, security e-mail account got deleted a while ago due to inactivity (hahaha)). I know my master password - but it doesn't help. I need this link sent to my deleted account). Did you finally get a solution?
