Hello, @Negin Kashkooli !
All of us have created a new account and forgotten our password at one point or another (although this is a good reminder to use a password management system or save your password somewhere safe). If none of the email recovery options work, you can still try to contact Azure support and use other forms of contact that have been associated with your account.
Assuming you were using an Azure free account, you won't be charged unless you make the decision to go to pay-as-you-go (which you won't do unless you have access to your account):

How do I ensure that I won't be charged?
We’ll never charge you unless you decide to move to pay-as-you-go pricing. If you move to pay as you go, you’ll only be charged for services that you use above the free monthly amounts. You can check your usage of free services in the Azure portal.
