Most common questions used to investigate
Once you delete your Instagram account everything you have posted will be permanently removed and you won't be able to sign up again with the same username. Would you like to temporarily disable your account instead?
Common conclusions
To temporarily disable your account, log into instagram.com from your computer or mobile browser click your profile picture, then click edit profile. Select 'temporarily disable my account,' select a reason from the drop-down menu, re-enter your password and then select 'temporarily disable account' once again.
To permanently delete your account, enter the 'delete your account' page from your computer or mobile browser, log in if you haven't already, select a reason from the drop-down menu for deleting your account, re-enter your password and then click 'permanently delete my account.'
