# Outdated TLS 1.2 cipher suites will be disabled on Supabase HTTP APIs

> Starting November 10, 2026, four CBC-mode TLS 1.2 cipher suites will be removed from Supabase project HTTP APIs. This primarily affects end-of-life operating systems and embedded devices; fewer than 0.0001% of current connections use these ciphers. Modern clients using TLS 1.3 or current GCM-mode ciphers are unaffected.
