Hear2Verify

This Chrome extension generates a unique verification code from a known email address and allows for verification over a phone call. To use it, simply right-click on the email, select 'Send Verification Email', and an email compose window will open with the selected email address as the recipient and 'Your One-Time Verification Code' as the subject. The body of the email contains three two-digit numbers separated by a space, which can be shared over the phone.
