A QR code is not required for Authy, as our integration with Authy all happens behind the scenes. As long as you are using a verified phone number that is associated with your Gemini account, the token should appear on your Authy account. If this is not the case, please head to Authy Reset page to reset your phone number with Authy. Once complete, please reach out to Gemini Support in order to update your phone number. This should allow for the token to appear in your app.
