In specific cases Instagram will ask for email confirmation at login. This allows Instagram to confirm you’re the owner of the email address in the account profile.
However, in some instances, even if Instagram says the confirmation email has been sent to you, the message is not there and, if more than 10 minutes passes without receiving any message in your inbox (make sure you also check the spam folder), it will most likely never arrive – unless you use the following solution:
Steps to get the Instagram email confirmation message
Step 1: Navigate to the Instagram login page / open your Instagram app, at the page where you need to login with an account, and click on forgot password;
Step 2: Proceed with a password reset for the account. The password change message should arrive in maximum a few minutes. However, at this point you may still not receive the password change email, so you need to repeat the steps 1 and 2 to send the email again.
Step 3: After receiving the email, click to reset the Instagram password, you’ll be redirected to Instagram to do so. (don’t forget to note it down somewhere);
Step 4: At the next login, Instagram will ask again for email confirmation, proceed with sending the verify email, and now the message should land in your inbox. Open the message and get the code or follow the link;
Step 5: Finish confirming the email by using the code or link found in the message;
After submitting the code, you should now be successfully logged inside your account.
