When you can’t login to Instagram it’s a major problem for you, but it is something that you can easily fix. The first thing to do is re-type your username and password and attempt to log in again. You can also try this on your computer.
In the app on iPhone or Android, you can choose to send an SMS or Log in with Facebook on Android or to send Login link on iPhone. This will help you log in with the right credentials easily.
A common issue when trying to reset Instagram password is: incorrect email account linked. If you have Facebook and Instagram you can reset your password with Facebook, which is an easy option for many users.
If your Instagram password reset email doesn’t work, you can try sending it again, and then make sure you don’t add any extra spaces to the link if you copy and paste it.
