I was previously from another country and at the time got created a Yahoo Mail.
I am currently living in Iran and sign out of the my mail.
For this reason, while sing in the my mail for security is said to be sent to the phone number of a code.
But I have lost my phone number now and I need my mail information.
How do I login? Help me please
