Aurora Store works without the default enabled account sharing feature. The account sharing feature is disallowed by Google's terms of use banning account sharing. We've warned about this very likely being banned for years and have recommended people make a purpose-specific Google account for this instead. Google often requires phone number verification for an account for anti-spam but many VoIP services work for it.
You can install the Play store from the GrapheneOS App Store.
In fact I'm pretty sure the GrapheneOS folks advise against Aurora Store, etc.
The problem is that even if you have separate google accounts on each android device, Google can still track you by looking at your contacts.
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.
Or you could go through the android phone sign-up process which doesn't require one. Buy a cheap android phone and keep resetting it and making a new account each time.
Or you could buy an account on the grey web from someone who already did this. Should be under $2.
If you are really into this you could become a phone company and own a whole block of phone numbers.

This is worse IMO because now the number is associated with that device forever. And unless I'm willing to risk my account to compromise from a future owner of the same number OR device, I must now keep both... forever.
> grey web
I don't want to give them my info either, nor have my account associated with sketchy individuals.
> you could become a phone company
I do own DID blocks but this is unhelpful because google's verification specifically requires SMS over real mobile numbers, and I'm not interested in becoming an MVNO or cellular carrier.
Perhaps you'd be more interested in creating a website that downloads all the apps from the play store using burner accounts and makes them easily anonymously accessible.
I used android sign up process to create my other dummy account I use in TV only for smarttube and app updates, that seems like great option if it still works
How could an account from a completely different company let you login to Google's Play Store???
You probably mean a Google account that uses your Proton mail address?
