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.

Hi ani450, sorry to hear that you're having trouble. If you no longer have your recovery codes, and you did not back up your account in Duo Mobile by setting a recovery password, you will have to report your account to Instagram and wait for the team there to help. Duo isn't able to add or remove 2FA for your accounts, nor can we recover your codes for you.

Hi there Alyeskaaaa, I'm sorry to hear that you are unable to log in to your Instagram account. Unfortunately, unless you have previously enabled and set up Duo Restore for Third-Party Accounts ( or if you generated and saved the recovery codes for your account ( we will be unable to assist with this. Please contact Instagram to regain access to your account. You will then need to reconnect Duo Mobile to your account manually following the steps here:

Be aware

I lost few of my accounts because this app decided to disconnect all of them. I have to reconnect my apps but can not do that without connected 2FA...
