2nd Portal email received today (<24 hours from 1st portal email). I replied with PR photos in 30 seconds. Nice and easy. One login for all dependants. Sweet !
IMPORTANT TIP -- DO NOT try to create portal login yourself. You will land into HUGE delays. Wait for the password from IRCC. (Experience from a WhatsApp group member).
Good luck. Once DM is received, everything seems to be lightening fast, atleast until eCOPR (this eCOPR is quite useless nowadays. Contains no useful info and is generic - it seems).
