Parameter filtering

When logging parameters, Phoenix can filter out sensitive parameters in the logs, such as passwords, tokens and what not. Parameters to be filtered can be added via the :filter_parameters option:

config :phoenix, :filter_parameters, ["password", "secret"]

With the configuration above, Phoenix will filter any parameter that contains the terms password or secret. The match is case sensitive.

Phoenix’s default is ["password"].
