Providing a telephone number during the Instagram account creation or account maintenance process represents a method for identity verification and account recovery. This form of contact information serves as a secondary confirmation point, supplementing email addresses to ensure the user is genuine and has a reliable way to regain access to the account if login details are forgotten or compromised.
The practice of associating a telephone number with an Instagram account enhances security protocols and reduces the incidence of fraudulent activity. It allows Instagram to send security codes via SMS for two-factor authentication, making it significantly more difficult for unauthorized individuals to gain access. Furthermore, in situations where an account is locked or requires verification due to suspicious activity, a registered telephone number expedites the recovery process and helps maintain the integrity of the platform. Initially, providing a phone number was optional; however, platform updates and evolving security needs have influenced its role.
