Customer-facing applications—whether they are aimed at consumers or business users—require a common set of fundamental features related to authentication, authorization, and user management. Applications need to support common workflows such as account creation, user login, password reset, account recovery, and multi-factor authentication (MFA) enrollment. Additionally, applications need to accommodate different levels of access depending upon the user.

This whitepaper features the key factors to consider when making a build vs. buy decision, as well as the advantages of a pre-built solution.
