When we talk about the internet, especially social media handles, cyberattacks & account compromises are all too common. Passwords alone are no longer enough, which is why  Instagram introduced Two-factor authentication to secure users’ accounts from unauthorized access and potential breaches.

Why is Instagram Not Sending SMS or E-mail Codes for Verification

Two-factor authentication is an additional layer of security that requires users to provide two forms of verification, usually a password and a unique one-time code sent to them, via SMS or email. Even though it is highly important as it keeps your personal information, photos, and messages safe, not being able to log in to your account due to it can be nothing short of an annoyance. 

Now here is why you might not be receiving the code:

  • Poor Internet Connection
  • Bad Network Coverage
  • Server Downtime Issues
  • Bugs and Glitches
  • Use of VPN
  • Blocked IP Address
  • Repeated Requests 

Tip: Double-check that the phone number associated with your Instagram account is correct, currently in service, and has an active plan to receive SMS. Moreover, avoid sending code requests too frequently as it can block the delivery of codes for security reasons. Waiting for a few hours can be helpful.
