Description

We are publicly documenting the signing certificate fingerprint that needs to be used with external services.

Motivation and Context

Customers were raising issues that services like Sign in with Google weren't working. This was caused by the app being signed with a new certificate and the new fingerprint not being registered with the service.

Types of Changes

  • Bug fix (non-breaking change which fixes an issue)
  • New feature (non-breaking change which adds functionality)
  • Breaking change (fix or feature that would cause existing functionality to change)
  • Documentation fix (typos, incorrect content, missing content, etc.)

We also have this page were we are documenting some side effects of resigning, https://docs.saucelabs.com/mobile-apps/automated-testing/ipa-files/#sauce-labs-resigning-enablements we might want to document this there as well. The title of the page is not the best unfortunately

edit: actually I'm just going to create a new page in our Features section documenting the resigning process

| Group Folder Redirect <br/><p><span className="sauceGreen">iOS Only</span></p> | Enable/disable a group directory redirect. Enabling allows you to use your app's private app container directory instead of the shared app group container directory. When your app gets resigned, the shared directory is not accessible. |

##### Android App Resigning and Certificate Fingerprint
When resigningEnabled is set to true (which is required for instrumentation features), Sauce Labs resigns your application. This re-signing process changes the app's signing certificate.

In the table above it's not called resigningEnabled, but Instrumentation

Suggested change
When resigningEnabled is set to true (which is required for instrumentation features), Sauce Labs resigns your application. This re-signing process changes the app's signing certificate.
When "Instrumentation" is enabled (which is required for instrumentation features), Sauce Labs resigns your application. This re-signing process changes the app's signing certificate.

| [Biometrics Interception](/mobile-apps/features/biometric-authentication/) | Enable/disable Biometrics Interception. Enabling allows you to choose authentication options if your mobile app requires a biometric authentication, such as fingerprint or face recognition on Android, and Face ID or Touch ID on iOS.<br/> This setting is disabled by default for iOS apps. |
| Group Folder Redirect <br/><p><span className="sauceGreen">iOS Only</span></p> | Enable/disable a group directory redirect.

I guess we can remove one level from all headings in here since there is no H1, we start with H2 for some reason 😕

Agreed. Yeah I didn't find a good place where to put it and Ahmed suggested to put it there. I think it is a good idea to add a dedicated Android Resigning page as well like you did for iOS.

Will update the PR with the dedicated page
