    This browser extension generates verification codes offline. Accounts can be added by scanning QR codes or dragging in files, and during login, you click to copy the code. It supports multiple languages. It manages multiple accounts with drag-to-sort and export backup features. The interface is clean and nice-looking. I use it now, and rarely open the phone authenticator.
