On Instagram you have the options of either deactivating and deleting your account.
You can either temporarily disable your account or permanently delete it.
If you temporarily disable your account:
• Your profile, photos, comments and likes will be hidden.
• You can reactivate your account by logging back in.
To temporarily disable your account:
• Log into instagram.com from a mobile browser or computer. You can’t temporarily disable your account from within the Instagram app.
• Tap or click your profile picture in the top right and select Profile, then select Edit Profile.
• Scroll down, then tap or click Temporarily disable my account in the bottom right.
• Select an option from the drop-down menu next to Why are you disabling your account? and re-enter your password. The option to disable your account will only appear after you’ve selected a reason from the menu and entered your password.
• Tap or click Temporarily Disable Account.
If you delete your account:
• Your account, profile, photos, videos, comments, likes and followers will be permanently removed.
• You can’t sign up again with the same username or add that username to another account.
• Deleted accounts cannot be reactivated.
To delete your account:
• Go to the Delete Your Account page from a mobile browser or computer. If you’re not logged into Instagram on the web, you’ll be asked to log in first (you cannot delete your account from within the Instagram app).
• Select an option from the drop-down menu next to Why are you deleting your account? and re-enter your password. The option to permanently delete your account will only appear after you’ve selected a reason from the menu.
• Click or tap Permanently delete my account.
