How can I recover my account without my email address?
Check your computer browser history
Many browsers automatically save passwords when creating or logging into an account. If you logged into your account on a browser, it's worth checking to see if the password was saved.
Check your phone’s saved passwords
A lot of phones allow you to save passwords for apps you’ve downloaded and websites that you’ve visited. If you think your information may have been saved, double-check your phone’s settings. If you can log back in, you can add your new email address to your account and reset your password.
