Also need to provide an email when using EAB

[rea1shane]

Welcome

• Yes, I'm using a binary release within 2 latest releases.
• Yes, I've searched similar issues on GitHub and didn't find any.
• Yes, I've included all information below (version, config, etc).

What did you expect to see?

When using EAB, no need to provide an email. I think email and EAB only need to provide one. Please correct me if I'm not understanding correctly.

What did you see instead?

When using EAB, also need to provide an email.

Get the email directly without checking EAB first.
