Its a purple-red-orange gradient app with a white, square, camera icon. If you're using an Android device, you cannot use your username to prompt Instagram to send you a password reset email. It's below the blue Login button. You may have to tap Sign in at the bottom of the screen first. If you don't remember which email address you used to create your account, typing in your Instagram username will at least give you a hint. A pop-up window with the first letter of your Instagram-registered email address and a confirmation message will appear. For example, you might see "We sent an email to m*******b@gmail.com with a link to get back into your account." It's at the bottom of the pop-up window. If you don't have access to the email address you provided, you'll need to use your phone number instead. Its subject will say "Help with your account," and you'll find a link below the Log Me In button entitled "reset your instagram password here." If you don't see an email here, look for it in the "Spam" folder (or the "Social" or "Updates" folders in Gmail). Doing so will take you to a page where you can type in a new password for your account. You'll enter it in the two text fields listed on this page. It's at the bottom of the page. If your passwords match up, you'll be taken to your Instagram home page in your mobile browser. You can now open Instagram and log in with your reset password.
