Q:

ssh to my compute engine machine

Two days ago I've created a compute engine instance and connected to it with ssh, everything was fine, after testing different things i've deleted the machine and disk.
Today I've created a new instance in compute engine, getinstance as well as the console show the instance running.
But when trying to connect to the instance I'm getting a messegebox asking for: enter your password for the ssh key "google compute engine"
the password i'm entering is getting denied
how can I change the password for this project? this user? 

A:

This is how I resolved the issue:

turn hidden files on on finder (by running: defaults write
com.apple.Finder AppleShowAllFiles TRUE) 
going to $HOME/.ssh directory and delete the files google_compute_engine, google_compute_engine.pub 
call gcutil ssh again which created new files with new passphrase
when prompted again enter the passphrase and connection established :)
