There is a great deal of difference between Yahoo account key and that of 2 step verification. While account key is designed to reduce your dependence on password, the 2SV or two-step verification plays a pivotal role in enhancing the overall security.
Let's Look at the overall difference.
Yahoo Account Key
With Yahoo account key, it becomes largely possible for you to access the inbox, for which there is no need to utilize any conventional password. However, you will need a smartphone with Yahoo mail app, installed on the device. When you enable the account key, it then sends a notification to your smartphone. Once you approve, you can straightaway access the account.
2 Step Verification
As far as 2 step verification is concerned, you are required to provide your phone number. On entering your phone number, you are required to confirm, whether you want the verification code through SMS or Call.
When you provide the correct phone number, you will then receive a verification code in your mobile. Make sure to enter the code and click on the verify button. From now on, every time you try to access the account, you are required to enter the verification code.
I sincerely hope the answers does provide you with a basic knowledge of the difference between Yahoo account key and that of 2 step verification.

use another device and request a password be sent to your backup email address you applied with. you could also stick your phone in warm dry rice and see if it dries out and works. Don't use it wet.
