This is a temporary password, by default valid for 3 hours.

The one you set with 'hosted-engine --add-console-password' is temporary
too, valid for 2 minutes.

Did vnc console connection work during deploy?

Do you have engine up and running? If so, can you get the console through
the web admin?

This all seems unrelated, result of some monitoring.

When I try to login with an invalid password, I get in vdsm.log:

If you do not see something similar, you might have some problem earlier.
