We understand that this is too late in this circumstance, but always create IMPORTANT accounts, such as email, and lesser important accounts, such as social media, on a landline workstation. A landline workstation can be laptop on wifi, or a desktop on wifi for that matter. The important thing; the account is created from a WIRED, NON-cellular network.
The provider can offer many ways to recover your account, if you create it in this manner. Always attach a recover email, such as a work, or another email that you will not forget the username and password to (because it SO important)!
After you have attached another email address in case of forgetfulness, now you can attach a mobile device to the account. Now, if you lose, break, or stop having access to your mobile device (non-payment of services), you can still recover your account!
Yahoo no longer uses secret questions, the system may ask for them but they no longer work.
Even if could help you remember your pet's name it would be useless.
Unfortunately, if, when you created your Yahoo account, you have not registered an alternate recovery email address to which you have access to receive an account key, you can’t prove that you are the account's legitimate owner. Hence account recovery is absolutely impossible and there is no way around it.
