Thank you for your post and I apologize for the delayed response!
When it comes to deleting or stopping the sync of passwords, in the Authenticator app, open Settings > Autofill settings > Sync account. On the next screen, you can select on Stop sync and remove all autofill data. This will remove passwords and other autofill data from the device. Removing autofill data doesn't affect multi-factor authentication.

If you have any other questions, please let me know.
Thank you for your time and patience throughout this issue.
