A. If you are having trouble accessing your account due to an incorrect email address, try using the 'Forgot Password' feature on the login page. Enter your email address, and if it’s recognized, you will receive a password reset link. If you do not receive the email, check your spam or junk folder. If you still cannot access your account, consider creating a new account with the correct email address if possible.

B. If you have access to the customer support section of the Fastweb website, look for an option to update your email address. You may need to provide some identification or account details to verify your identity.
