 When Codex asks a question, choose a numbered option (or `o` for a free-form answer when offered)
 and the client will send the response and continue streaming the same turn.
 
+## Testing Codex-managed Amazon Bedrock login
+
+`test-login --amazon-bedrock` initializes the experimental app-server API, sends an
+`account/login/start` request with an Amazon Bedrock API key, and waits for the
+`account/login/completed` and `account/updated` notifications. Login replaces the current primary
+credential and sets `model_provider = "amazon-bedrock"`, so use an isolated `CODEX_HOME` when
+testing.
+
+```bash
+export CODEX_HOME="$(mktemp -d)"
+printf 'cli_auth_credentials_store = "file"\n' > "$CODEX_HOME/config.toml"
+
+cargo build -p codex-cli --bin codex
+cargo run -p codex-app-server-test-client -- \
+  --codex-bin ./target/debug/codex \
+  test-login \
+  --amazon-bedrock \
+  --api-key "<BEDROCK_API_KEY>" \
+  --region us-west-2
+```
+
+The test client redacts `apiKey` from its outbound request log. After login, start a fresh Codex
+process with the same `CODEX_HOME` to verify that it uses the persisted managed credential.
