 Set `browser.region` to choose where Managed Auth runs the connection's initial login, health checks, and automatic reauthentication. Choose from `us-east`, `eu-west`, and `ap-southeast`. Region selection is available on [Start-Up and Enterprise plans](/info/pricing); omitted values default to `us-east`.

+Updating `browser.region` or `browser.location.locale` changes the connection default for browsers created afterward. It doesn't move or restart an active login, health check, or reauthentication browser. When you update the locale, omit `locale` to keep its current value or set it to `null` to clear the override and return to the region's default. You can't override the locale on `.login()`.
 
 You can override the connection region for one login without changing its default:
