To gain access to Instagram profiles without creating an account, you can use third-party Instagram viewer tools. These tools allow you to search for and view public Instagram profiles without the need for a personal account.

If you forget or don't know your Instagram username, you can still log in using your phone number or email address associated with your account. Once you log in, you'll be able to find your username at the top of your profile.

You can access your Instagram account on the web by going to instagram.com and logging in with your Instagram username and password.
