# Set the location of the bootstrap secret.
# Can be "local_manager" or "memory", depending on how you setup the bootstrap secret.

# If your operating system is NOT Windows or MacOS/iOS, then change "local_manager" to "memory"
# You can also, if desired, use "memory" on Windows and MacOS/iOS if your bootstrap secret was previously setup in memory.
