All Apple Developer accounts now require 2FA to be enabled. Read how you can manage this on Bitrise.
Whenever you need to communicate with App Store Connect during a build on Bitrise, we have to solve the two-factor authentication somehow. This is not convenient (this is an understatement, right?), especially for an Automated CI/CD system.

When do you need to communicate with the App Store Connect?
- If you want to generate/manage a Provisioning Profile (using the iOS Auto Provision step)
- If you want to upload your app to the App Store (iTunes Connect Deliver step, Fastlane)
- If you want to upload some metadata, screenshots, etc. via Fastlane and so on...
Our solution
If you connect your Apple Developer account to Bitrise, we will be able to re-use its session for our steps.

Until now only the iOS Auto Provision step supported this solution, but we've added this feature to the iTunes Connect Deliver and to the Fastlane steps as well.

So you are able to upload and update your iOS apps on Bitrise even with an Apple Developer account which has 2FA enabled.
Please note: If you want to use Fastlane with the 2FA enabled, then you will need to use our Fastlane step.
