I just tried setting up a Tranquil PDS instance with SSO-only login / registration (well, as much as that's possible right now) and have come across the problem that even though i've set disable_account_verification_gate = true in my config.toml, Tranquil still requires account verification. As no comms channel has been configured there is an respective error logged:
2026-06-26T19:30:31.795852Z WARN tranquil_pds::comms::service: No sender registered for channel comms_id=8bc84874-bea7-4485-b5d7-a890c5a1a6a4 channel=Email
2026-06-26T19:30:31.795894Z WARN tranquil_pds::comms::service: Failed to send comms comms_id=8bc84874-bea7-4485-b5d7-a890c5a1a6a4 error=Channel not configured: Email permanent=false
A verification code still gets generated and grabbing it directly from the database to verify the account worked. Setting an email address for the new account is also still required.
