Use the Duo invite page to invite a friend by email after subscribing to a Duo plan.
Enter your friend's email address. You can add their name too, but that field is optional. Submit the form and wait for the confirmation, which shows the address the invite was sent to.
Your friend receives a private invite code by email. They enter the code when Bo asks during onboarding. The code is for the invited friend, so don't share or forward it.
Check that the email address is correct, then try again if the page allows it. Ask your friend to check their spam or junk folder. If the invite still does not arrive, contact Bo support at [email protected].
