- The X-Auth-Token is sensitive data. If revealed to an unauthorised person, they can now make requests against an account until the token expires. Set reveal_sensitive_prefix to the number of characters of the token that are logged. For example reveal_sensitive_prefix = 12 so only first 12 characters of the token are logged. Or, set to 0 to completely remove the token.
- By default, the X-Auth-Token is logged. To obscure the value, set reveal_sensitive_prefix to the number of characters to log. For example, if set to 12, only the first 12 characters of the token appear in the log. An unauthorized access of the log file won't allow unauthorized usage of the token. However, the first 12 or so characters is unique enough that you can trace/debug token usage. Set to 0 to suppress the token completely (replaced by '...' in the log).
.. note:: reveal_sensitive_prefix will not affect the value logged with access_log_headers=True.
