Nsupdate.info token?

Good.

I have tried to find the group it belongs to but I have not found any suitable one. I already feel it.

A somewhat stupid question. What should I put in TOKEN when I configure the DynDNS of nsupdate.info ?. I’ve tried various things but it doesn’t seem to accept anything I put in. He always puts:

"Password not set"

Thank you.

Greetings.
