Optional Email Verification Code Autofill

[umairx25]

Overview

On iPhones, iOS can automatically detect verification codes received through Gmail or Apple Mail, and suggest them directly in verification fields, eliminating the need to manually switch apps and copy codes. I propose bringing a similar experience to Firefox as an optional, built-in autofill feature.

Proposed Functionality

Firefox already provides optional autofill functionality for information such as addresses, passwords, and payment details. Email verification code autofill could be introduced as another opt-in setting within this existing system.

How it would work:

1. Opt-in settings: Users enable verification code autofill in Firefox's settings and authorize the email accounts they want to use.
2. Field detection: Firefox detects when the user is interacting with a verification code input field.
3. Code retrieval: When the user clicks the field, Firefox checks authorized inboxes for recent, relevant verification codes.
4. Autofill suggestions: If a matching code is found, Firefox displays it through the existing autofill interface for one-click insertion.

Existing Proof of Concept

I've developed CodeFill, a browser extension that retrieves verification codes from Gmail and simplifies copying them during authentication.

The extension is already published on the Chrome Web Store and has received over 250 installs within its first month. Much of the underlying functionality, including Gmail integration, verification code retrieval, and code extraction, has already been explored through this project.

• GitHub: CodeFill source code
• Chrome Web Store: CodeFill extension

I'd be interested in contributing to the implementation and would appreciate feedback on the feasibility of integrating this feature natively into Firefox.
