Below is a past Post by IRCC:Good morning everyone, please I need help this morning any suggestions you have I will really appreciate. So a friends of mine is applying for student visa and she accidentally put in wrong answers for her security questions when login, now the account it locked and it says it can’t be recovered online anymore. As anyone experienced such or knows how we can go about it. I also researched that if we open another one we have a risk of losing both accounts. Please help
"If your account is locked, you'll be able to access it again in 24 hours. Note that if you forgot the answers to your security questions, you'll have to make a new account and link your application from it"
