Identity verification typically involves multiple steps:
1. Email Verification: This step ensures that the email address is valid and active. Tools like email verification APIs can be used to check the syntax, domain, and mailbox. 2. Two-Factor Authentication (2FA): Adding an extra layer of security by requiring a second form of identification, such as a text message or authentication app code. 3. Domain Authentication: Techniques like SPF, DKIM, and DMARC ensure that emails are sent from verified domains, reducing the risk of email spoofing.
