We don't recommend the Play Store as a source of apps in general. For obtaining apps from the Play Store, we primarily recommend using our sandboxed Play Store feature. Aurora Store is mainly useful for working around Play Integrity API store listing restrictions.
Aurora Store can be used without the shared account feature. The shared account feature was on track to getting blocked for years and we've warned about it. Sharing accounts is against the Google terms of use and they've been ramping up their detection and banning of it. It's somewhat strange they allowed it to go on for so long. Aurora Store does still work as an alternate Play Store frontend since Google hasn't blocked that.
Due to Aurora Store bypassing the Play Integrity API store listing restrictions, they may decide to take steps to hinder it. It's a very easily bypassed way of using the Play Integrity API but it harms alternative operating systems.
