From 4dbca37085263a3336ed88d65d72fb6350e6d8e5 Mon Sep 17 00:00:00 2001 From: Paul Faure Date: Mon, 9 Feb 2026 18:19:58 -0500 Subject: [PATCH 1/3] fix(appauth): skip expired tokens before bcrypt and purge on load Every authentication request ran bcrypt.CompareHashAndPassword against ALL stored tokens, including expired ones. Since bcrypt is intentionally slow (~70ms at cost 11), a user with many expired tokens experienced significant latency on every auth request. Changes: - Check token expiration before bcrypt comparison in GetAppPassword - Use RWMutex instead of Mutex to allow concurrent reads - Purge expired tokens on startup and during GenerateAppPassword - Extract isExpired() helper for consistent expiry checks Co-Authored-By: Claude Opus 4.6 --- pkg/appauth/manager/json/json.go | 123 ++++++-- pkg/appauth/manager/json/json_expiry_test.go | 284
