An authentication method that passes credentials in HTTP headers rather than using secure cookies. In LogScale, bearer tokens serve as an alternative authentication mechanism when the web frontend and backend API must be served from different domains with no subdomain relationship, making secure cookies impractical. While functional, bearer token authentication is considered less secure than cookie-based authentication because tokens are transmitted in HTTP headers with each request and may be more vulnerable to interception. Bearer token authentication can be enabled in LogScale using the ENABLE_BEARER_TOKEN_AUTHORIZATION configuration parameter.
