Add VERIFY_AND_CHANGE_EMAIL Mail Link Support #704
Description
Description:
The Node.js Admin SDK has the generateVerifyAndChangeEmailLink method which allows generating action links for email address changes with verification. However, this method is missing from the Go Admin SDK.

Current situation:
- Node.js SDK has generateVerifyAndChangeEmailLink() (since v10.2.0)
- Go SDK only has EmailVerificationLink() which doesn't support email address changes
- Client SDKs generate links with mode=verifyAndChangeEmail
Use case:
When implementing email address change functionality, we need to:
- Send a verification link to the new email address
- Upon verification, update the user's email address
- Ensure the new email address belongs to the person requesting the change
Current workaround:
We have to implement custom token-based verification system, which adds complexity and potential security risks.
Request:
Add GenerateVerifyAndChangeEmailLink method equivalent to the Go Admin SDK to achieve feature parity with Node.js SDK.
Proposed
func (c *baseClient) EmailVerificationAndChangeLinkWithSettings(
ctx context.Context, email string, settings *ActionCodeSettings) (string, error) {
return c.generateEmailActionLink(ctx, emailVerificationAndChange, email, settings)
}type linkType string
const (
emailLinkSignIn linkType = "EMAIL_SIGNIN"
emailVerification linkType = "VERIFY_EMAIL"
+ emailVerificationAndChange linkType = "VERIFY_AND_CHANGE_EMAIL"
passwordReset linkType = "PASSWORD_RESET"
)
