On the Books tab, Sodium asks where the client does their accounting and offers the accounting platforms it supports - Xero, QuickBooks, FreeAgent and Sage. Pick one and you connect through secure OAuth; no API keys and no shared logins.
If your practice already has a connection to that platform, Sodium lists the organisations it can see and you simply choose the client's. If they sit under a different login, sign in with those credentials instead.
