Build an omnichannel OTP verification flow

How it works

• Receives user identity data from multiple channels (WhatsApp, Telegram, email). • Generates and stores secure one-time passwords (OTP). • Validates OTP codes against Postgres records. • Centralizes user identity across channels. • Maintains session continuity for onboarding and verification.

Set up steps

• Import the workflow into n8n. • Configure Postgres or Supabase credentials. • Download and create the required database tables in Supabase. • Connect messaging channel credentials. • Define OTP expiration and validation rules. • Test using sample user verification scenarios.
