# id OAuth authentication service for ByeCorps & other services ## Development & deployment ## FAQ ### What is a ByeCorps ID? A ByeCorps ID (BCID) is a seven digit alphanumeric (non-case sensitive) code used to identify a person. It is used to reduce the need of multiple accounts across ByeCorps services, as well as third-party services using OAuth (though a password alternative is recommended instead of BCID only) Example of a BCID: ```txt 123 ABC4 ``` ## Canonical domain names Only input your BCID on the following domain names ONLY on a HTTPS connection: - https://id.byecorps.com Any other domain name or an insecure connection might be a phishing attempt, so be careful. **NEVER** input your BCID password on any other domain.
