Sorry for the misunderstanding.
I will resume here what I`ve tested on Friday:
- I signed in with the same Firefox account on desktop, Android, and iOS;
- I`ve created some "Saved Logins" on Desktop on the following links: https://news.ycombinator.com/login, https://www.facebook.com, https://twitter.com, https://en.m.wikipedia.org, https://www.amazon.com, https:www.linkedin.com and forced sync;
- On Android/iOS, forced sync, then modified the username and password for one of the created login and force sync;
- On Desktop, forced sync.
- I also did the editing on Desktop, forced sync, then observe the behavior on Android/iOS.
The login username and/or password had changed to whatever was typed on the Android/iOS devices. None of the saved logins disappeared after the editing.
Environment: Windows 10, OnePlus 5T (Android 9), iPhone SE (12.1.4), Samsung Galaxy S8 (Android 8.0)

I have tested following the steps from Comment 9, with Samsung Galaxy S8 (Android 8.0), OnePlus 5T (Android 9.0), and Windows 10, on Nightly 67.0a1 (2019-03-08). The issue did not reproduce.
These other scenarios were extra testing, to verify that sync worked as expected.
I also tested with other scenarios:
After signing in on both, Android and Desktop, from the Manage Account page, I changed the password on Android. On Desktop, I was signed out automatically, and I signed back in using the new password.
I tapped on Forgot password link on Android, went to email, and reset the password. On Desktop, I was signed out automatically, and I signed back in using the new password.
All three scenarios suggest that sync worked when the password was changed.
I will mark this issue as fixed, and remove the [qa-triaged] flag.
Wait, this has nothing to do with #c9. This is changing an account password for a single site/service, Firefox Accounts. #c9 is about editing saved logins in the Firefox for Android product and ensuring they are synced to other products, i.e., Firefox for Desktop and for iOS. And indeed that the edited login is used in autofill on the originating Firefox for Android device. For example, you might test with a Facebook account or a Spotify account.
miralobontiu: do you understand how these are different?
Yes, I`ve tested multiple scenarios, but please let me know if there is a different way to test this issue.
