After choosing to deactivate your account, Instagram typically requires a few hours to finish the process. During this time, you cannot reactivate your account. If your account has been deactivated for more than a day, you should be able to log back in without any trouble. If you chose to delete your Instagram account, you won't be able to reactivate it after deletion. Tap the Instagram app icon, which resembles a multicolored camera. Do so in the top text field. You can use any of these credentials so long as they're associated with the account you want to reactivate. Depending on the screen to which Instagram loads, you may first have to tap a Log In button or link in order to view the login page. Do this in the "Password" text box. If you don't remember your password, you'll need to reset it. It's at the bottom of the screen. As long as your login credentials are correct, doing so will log you into Instagram and reactivate your account. Depending on how long your Instagram account has been deactivated, you may have to accept updated Terms of Use or verify your phone number before you can proceed to your account. Logging back into your account reactivates it, so you shouldn't have to perform any reactivation steps after logging in.
