But he said in the video he got no e-mail for other logins... where can you do that in that case?
In other old login e-mails is the same link to can lock it down (from what i see is a different link every time)?

Why isn't a way from the account to cancel all current transactions and lock account?
Anyway, to have locked account and don't know what is happening there is still bad, in a way. It could be ok to have at least a just viewer to your account to be able to see what's happening.

Eh... hope it's not happening again.
Watch what you share.
