Description

GitHub allows for users to add multiple emails, listing one as the "primary" email. This is useful as it allows users to have various GPG keys with different emails associated with an account without having verification issues.

This feature is essential for Gitea's verification, as right now my commits are showing as unverified, because the email used to sign them is different than the one associated with my account.

Gitea already does support multiple emails, see user settings

Sorry about that. I saw on the landing page for the settings that there was one "Email Address". Why are there two UIs for the same thing?

It just historicaly how it was easier to add. GitHub also has it this way

[RyanSquared]

GitHub has a dedicated section for managing emails. Not sure whether that's new or not with the redesign. GitHub also mentions that it's the "primary" email, which indicates you can have at least a secondary.

Onto another issue, it appears as though only one email is being parsed from my key. GitHub says the key is: "Email addresses: ryan@hashbang.sh vandor2012@gmail.com" I know that I ran gpg --export --armor ryan@hashbang.sh, but after putting it into Gitea, it was listed as vandor2012@gmail.com.

To clarify on the issue: Gitea expects the key to be made from vandor2012@gmail.com. However, the signature is parsed as coming from ryan@hashbang.sh
