To Test

1. Test the unified and old UI with 1Password enabled.
2. Test the unified and old UI with 1Password disabled (Toggle this from WordPressAuthenticationManager).
3. Please test on a physical device to see that 1Password is passed the domain correctly. I couldn’t test this specific part as I’m testing using a custom app ID to get around code signing issues, so the associated domain isn’t linked to my version of the app. However I checked the association file here and it seems everything is setup as expected.

Regression Notes

1. Potential unintended areas of impact
   No changes of significance. All changes are inside WordPress Authenticator.

2. What I did to test those areas of impact (or what existing automated tests I relied on)
   Tested the UI changes in WordPress Authenticator manually and added unit tests inside the helper framework.

3. What automated tests I added (or what prevented me from doing so)
   As AutoFill Password and 1Password are not available on simulators, I wasn’t able to add UITests to cover my changes.

PR submission checklist:

• I have completed the Regression Notes.
• I have considered adding unit tests for my changes.
• I have considered adding accessibility improvements for my changes.
• I have considered if this change warrants user-facing release notes and have added them to RELEASE-NOTES.txt if necessary.

This is temporary. Should be replaced with new version once the changes in WordPressAuthenticator-iOS are released.
