VerifyFill is a Chrome extension that checks your Gmail for verification codes and confirmation links, then offers to drop them into whatever page you're signing into. Read-only. Local. No server.
Get it for Chrome Free · unpackaged install from GitHub releases
Install the extension and sign in with the Google account that gets your codes.
Go to a site that wants a verification code or tells you to check your email.
When a match turns up, a small prompt appears on the page. Click it. Done.
VerifyFill needs read-only Gmail access to find codes. It reads your email address to show which account is connected. That's it — no VerifyFill backend, no ads, no selling data. Mail never leaves your machine except through Google's own API.
