Can't Find the IAT Form's User ID and Password? Here's What to Do

Losing your user ID and password can be stressful, especially when you're trying to manage your application details. If you're facing this issue, you're not alone.

Real Example:
A Reddit user in r/iiser shared, "I have the application ID noted, but the user ID and password were in my mail. I looked through all the mail, and suddenly it's no longer here. I couldn’t log in or reset my password because login is no longer available. Will I be ok, or is all hope lost?"

It's frustrating, but there's usually a way to work around it. If you've lost your login credentials, here's what you can do:

Check Spam/Junk Folders: Sometimes, automated emails containing login details might land in the spam or junk folder. It's always worth double-checking these folders.

Contact Support: Reach out to the examination or university support team immediately. They often have a recovery process for lost credentials and will assist you in retrieving your login details.

Be Prepared for Hall Ticket Release: Some platforms allow you to retrieve your login details or reset your password when the hall ticket is released. Ensure you keep your application ID handy and stay alert for any instructions sent by the exam authorities.

Tip: Don't panic! Lost login credentials are not the end of the world. Institutions usually have recovery systems in place. Just keep an eye on your email and the exam website for updates.
