Hi Dkd@1018, Congrats. If you received the first email from IRCC, Reply to their questions and choose option A or B. They should be the one who creates your profiles.
"A new account should only be created if you are starting a new permanent residence application using this portal. If you are only using this portal to confirm your permanent resident status and receive your permanent resident card, IRCC will create an account for you and email you your username and temporary password. For more details on the confirmation process, visit the permanent residence confirmation".
