@Killjoyz InfluxDB 1.x and 2.x use different authentication methods. To connect to a 1.x instance, you need to use the 1.x influx CLI. This should be packaged with your InfluxDB 1.x binaries. The 2.x CLI should only be used with InfluxDB 2.x.
No, the influx v1 shell command starts a InfluxQL REPL that connects to an InfluxDB v2 instance using the v1-compatibility API. This API lets InfluxDB v1 clients connect to and use InfluxDB v2.
