When you've just reinstall BigV on a new machine, you'll need to tell it who you are, and what account to use. It is a little more involved (for the computer) than just storing your username and password, so we call it "profile generation" rather than "logging in".

You can do this with the "profile generate" command like so:

$ bigv profile generate
What is your username?  matthew
What is your password?  (hidden)
What is your password again, for confirmation?  (hidden)  
What is your account name?  matthew
Please press your V-Key's button now: xxxxxxxxx
Profile generated. You can now access the BigV cluster as matthew.

You can now use the rest of the BigV commands as normal. If you have got your user name, password or V-Key wrong, you will see this message:

Your request was rejected by the BigV cluster as being unauthorized.  Please
check your credentials, and try again if you're allowed to do this.  If you know
you're not allowed to do this, please stop!

If you have forgotten your password, or lost your V-Key, we do not yet have an automatic password reset function - you will have to contact support@bigv.io and we should be able to get your account access back within 24 hours.
