Duo Mobile works with Duo Security's two-factor authentication service to make logins more secure. The application generates passcodes for login and can receive push notifications for easy, one-tap authentication on your iPhone, iPad, or Apple Watch.

Additionally, you can use Duo Mobile to manage two-factor authentication for other application and web services that make use of passcodes.

Note: For Duo accounts, Duo Mobile needs to be activated and linked to your account before it will work. You will receive an activation link as part of Duo's enrollment process. You may add third-party accounts at any time.

Seciurity codes not working

I can’t open my ig account. The seciurity codes don’t seem to work

Developer Response ,

Hi there, I'm so sorry to hear that you aren't able to access your Instagram. Did you recently change your IG display name or perhaps temporarily disable your account? either of those things may disrupt the connection between Instagram and the two-factor authentication app (in this case, Duo Mobile) that you are using. You must reconnect your account to the app in order for passcodes to work again. Do you have the recovery codes Instagram provides when you first set up 2FA? If not, you will need to contact the Instagram support team. Please take a look at this article for more details:
