I have this occasionally and think it is triggered because someone used your email address as their "backup email address". It shouldn't have any effect on your account but it is best to unlink it.
I already unlinked it as soon as I checked my email and saw what happened. Probably is as you say , someone used my email address as their recovery address but why me, that's why I don't understand, he/she whatever is won't get any help from me no matter what. Thank you all for your advice , am locking the thread right now. I checked my crypto-related stuff all is OK, so I guess I am fine. If some nasty shit happens I will ask again for help here.
