Why Is the OTP Not Received on Email for 2FA?

A one-time password (OTP) is not received through email for two-factor authentication (2FA).

Ensure that you have entered the correct email address.
Check your spam or junk folder for the OTP email.
Ensure that the MoEngage domain is whitelisted by the IT team.
Ideally, the OTP Verification page looks like this:
If the 2-Step Verification page shows a warning message, set up a 2-step verification on your device. The warning message states: "WARNING! Your admin has enabled 2-step verification for your account. Please set it up on your device to continue access."
