Query if user has community access?

Question

I want to implement the selfreg Napili community form of salesforce for that I want to add a step "If User has a user than to redirect to the 'forgot password' page"

So I need a step to ask something like If User In (Select id, name from Communitymembers where Community name = MyCommunity)

can u advise on best practice on doing so?

Thanks in advance! Idan Touito

If user's profile is added as member in community then you can query result on object "NetworkMember" where NetworkId field is community id.
