Context	Security & Privacy / Customer Identity and Access Management Software	Security & Privacy / Customer Identity and Access Management Software
Customer authentication experience	87Branded registration and sign-in plus OIDC, OAuth 2.0 and SAML federation cover the documented customer authentication paths; teams using SMS should pair it with another primary factor because SMS is limited to MFA.	87Registration, login, password management, ID verification, passkeys, phone login, magic links, and one-time passwords cover the stated customer access workflows across web, mobile, and kiosks; buyers should validate the flow against their own channel and recovery requirements.
Customer auth policy security	88Conditional Access and multifactor authentication support customer access policies, while SMS is an add-on for MFA rather than a first factor; buyers should select controls that match their sign-in policy.	85Risk-based authentication can trigger adaptive multi-factor checks for suspicious activity, and the enhanced-security option adds AI/ML protection and a dashboard; buyers needing those additions must include the separately priced option in their offer.
Customer profile and identity control	76Customer registration and REST authentication extensions support identity workflows that call application-defined business logic, while teams should map their profile and account-linking needs to the application design.	82Self-service profile management, preference controls, and delegated administration support customer data updates, while the supplied facts do not establish account-linking or identity-data-quality controls; buyers should verify those needs in their target implementation.
Consent and privacy readiness	78Go-Local offers exclusive data storage in Australia or Japan for external tenants, with the region fixed at tenant creation; buyers should settle residency needs before provisioning and confirm their consent obligations.	76B2C Core captures consent for one terms-of-service document and one privacy policy, while unlimited policies, preference management, and a seven-year audit vault require the separate consent option; buyers with broader consent operations should confirm its scope and price.
Scale and developer fit	82REST authentication extensions and listed Azure App Service and Visual Studio Code integrations provide defined application connection paths, while linked tenants share MAU counts for billing; teams should validate capacity and usage forecasts against their deployment design.	82REST APIs, webhooks, regional storage selection, site-group single sign-on, and described bidirectional integrations support implementation across the stated systems; buyers should validate performance and synchronization behavior on their own workload because those operating measures are not established here.
