What
Claude Code links a local computer (a "device") to your account by storing a device key. Previously, if that registration failed because a different key was already stored for the device, there was no way to recover. Now Claude Code detects this key conflict and asks you to confirm re-registering the device. If you confirm, it retires the old stored key (retrying that removal a bounded number of times if needed) and then re-binds the device with a new key.
Why
This fixes a dead end: a device whose stored key had gotten out of sync with the account could previously fail to register with no recovery path. A tengu_device_reenroll telemetry event records whether you confirmed the re-enrollment, so this new flow can be tracked.
