Reposit Power offer the ability to generate and use API Keys in favour of username/password when using the Market API. These API keys a suited for use when using the Market API as they have an indefinate expiry ensuring you do not have to regularly re-authenticate with the API - as such these keys must be securely stored. API Keys may also whitelist IP addresses that they are valid to be used from therefore providing a second factor of authentication.
API keys for the Reposit Market API can be generated by first logging in to Reposit Fleet. Once you ahve logged in click your username at the top right and then select "User Settings"
