This is how the toml file looks like

defaultZone = 'at-vie-1'
key = 'test'
name = 'Test'
secret = 'test2348198test'
sosendpoint = 'https://sos-{zone}.exo.io'

[[accounts]]
defaultZone = 'at-vie-1'
key = 'test2'
name = 'test-2'
secret = 'test3'
sosendpoint = 'https://ppsos-{zone}.exo.io'

After the user switch the account

go run . config
Use the arrow keys to navigate: j k l h 
? Configured accounts (* = default account):
  >Test*
    test-2
    <Configure a new account>

defaultZone = 'at-vie-1'
key = 'test'
name = 'Test'
secret = 'testkey'

[[accounts]]
defaultZone = 'at-vie-1'
