Storing a key and secret

There are 3 ways to specify a key and secret when a command. They are listed in order of priority:

  • command line parameters (-k, --key, -s, --secret)
  • environment variables (OPTK_KEY, OPTK_SECRET)
  • local .optk file (see below)


You can use any combination of the above, but note the priority of which values are read. For example:

$ OPTK_KEY=12345 OPTK_SECRET=abcdef optk session --key 67890
