Identity and Access Systems
Identity and access systems: single sign-on across connected applications, custom two-factor verification, multi-step identity checks, and passwordless access that removes account friction.
Single sign-on
One login across connected applications, with centralized control over who reaches which tools.
Two-factor verification
Custom 2FA with full control over security policy and no per-user subscription fees.
Identity verification
Multi-step applicant screening without storing sensitive personal data on your servers.
Passwordless access
Secure access without accounts or passwords, removing the friction that discourages submissions.
84EM matches authentication to the risk being protected
Login systems fail in two directions. A financial application that’s too weak grants access without knowing who’s applying. A store owner facing too much friction abandons a listing update rather than create another account.
84EM builds authentication fitted to what’s being protected. Single sign-on works where members move between connected tools. Multi-step identity verification applies where regulations demand it. Passwordless flows fit where the account itself was the obstacle.
Custom where custom is worth it
Third-party authentication services charge per user, cap what policies you can set, and put a vendor between you and your login flow. Sometimes that trade is fine.
When it isn’t, a custom build eliminates the subscription and returns full control. One client replaced a third-party 2FA service with a custom text-message system for exactly that reason. Sensitive data raises the same question: 84EM has built identity verification that screens applicants for a financial institution without storing personal data on the client’s own servers.
What 84EM Builds for Authentication
Single sign-on
Single login access across connected applications with centralized administration of who can reach which tools. Built for platforms where members use several systems.
Custom two-factor verification
Text-message and multi-step login verification with full control over security policies and no ongoing per-user fees.
Multi-step identity verification
Automated applicant screening before access is granted, designed so sensitive personal data never lands on your servers.
Passwordless access
Secure, account-free management flows: verified access through time-limited links instead of credentials, improving completion rates for the people who use them.
Proof of Work
Single Sign-On Access to Connected Applications for an AI Platform
An AI platform needed members to access multiple connected applications without logging in separately to each one. A single sign-on system replaced fragmented logins with one-click access and gave administrators centralized control over who can reach which tools.
