We regularly see requests from folks who are trying to sign in to their Republic account but believe that they are unable to because they’re waiting for a text or email with their Multi-factor authentication sign-in code. This is not the way it works with Republic. MFA codes send by text or email are not particularly secure and Republic has chosen to go the authenticator app route instead.
When you set-up MFA for your account you would have done so using an app like Google Authenticator or Authy (there are many such apps). When you need to retrieve the code you’ll open whichever app you chose and use it to retrieve the code you need.
Easy as pie.
