Accont locked spam

After last patch i have to visit my mailbox everyday to unlcock client, everyday client say "somone trying or login to your account from other location..."

Frist of all, i dont share my account,and nobody try to login, i have no idea why every day i have unlock my account. I dont have problem with unlocking account via recive key on mail box and using it, hovewer fact that my acccount is locked every day is very annoying, espetialy because i never share my account with any person, and nobody got acces to my accont.
