# Why does Omron login fail outside the US or EU?

Omron splits accounts by regional backend, and Terra integrates only the **EU cloud** (`OMRON`, ohiomron.eu) and the **US cloud** (`OMRONUS`, ohiomron.com).

Accounts registered on other regional backends (for example APAC or LATAM/Mexico) authenticate against a separate API that Terra does not have access to, so they **fail at login** (often a generic or 'incorrect password' error) even with correct credentials. Supporting more regions requires a dedicated partnership with Omron, so users should connect with an account from a supported region.

For **region-agnostic blood pressure**, use:

* Apple Health or Health Connect via the [mobile SDKs](https://docs.tryterra.co/health-and-fitness-api/mobile-only-sources) (any cuff pairing with the OS health app).
* Withings (single global cloud).
* Garmin Index BPM.
