How to prevent override of passwords during sync?

Hello @alechko thanks for reaching out to us.

When you sync, the most up to date information should be synced, not older passwords. I suspect 1Password 7.7.2 may be the culprit here. We fixed some sync issues in 7.7.3 and the most up to date version is 7.9.1 which includes this fix as well as lots of new features and improvements.

You can navigate to the 1Password page in Google Play and tap "Update" to update to the latest version.

If you find syncing your Android device changed other passwords you can sign in to your account on the 1Password website to find the password history. Click Home, select a vault and then the effected item. From there you can click Show Previously Used Passwords to see the item's password history and make any necessary changes.
