Two-factor authentication is the best possible way to secure your any account. Many big giants like Google, Microsoft, Facebook has moved towards this authentication process some years back. Instagram is behind this trend, but it seems like the favourite photo network app of this generation is finally getting with the time.
Users should keep an eye on the Instagram updates; because the current security pattern of Instagram is not a highly secure one. The surprising thing for anyone in the infosec industry is; why it took so long for such a big company to introduce this feature. Facebook who are the developers of Instagram are using two-factor authentication from past four years.
If a celebrity is targeted on instagram it may lead to deletion of photos, attack your friends and spam the feed with ecommerce products and scam offers. Such a thing could be quite annoying and recovering the account without any special measure could prove extremely tough.
Currently, the instagram lacks firm security features. If you increase your account security nobody can see your photos just like Facebook privacy features. Plus one cannot download the photos of other on instagram.
