Cheapest verified plan per vendor, monthly USD list price. SSO users: Amazon Cognito, Supabase Auth and Firebase Auth / Identity Platform bill SAML/OIDC per SSO user, not per connection (first 50 free, then $0.015 per SSO user a month). Their SSO results here assume 200 SSO users per connection (5 connections = 1,000 SSO users). See how 1,000 or 2,000 per connection changes the result or set your own. How we calculate this.
