IAM Services

Every SaaS app and internal system keeps its own accounts, so IT adds and removes accounts one system at a time. Japanese identity and access management (IAM) services centralize sign-in, access rules and the account lifecycle.

Most are cloud identity providers, known as Identity as a Service (IDaaS). An employee signs in once and reaches connected apps over SAML or OpenID Connect. The provider enforces MFA, limits access by IP address, time or device, and provisions accounts, creating and disabling them in each app as staff join and leave.

Alongside them, authentication servers add MFA to VPN and virtual desktop logins. API backends handle OAuth 2.0 and OpenID Connect for developers building customer logins.

AD Sync
Users and groups sync from an on-premises Active Directory, usually through a connector on the AD side, so staff keep signing in with their Windows credentials.

Device Certs
Only devices with an installed client certificate can sign in, so a stolen password alone fails on an unknown machine. Each new device needs a certificate first.

FAPI
Support for Financial-grade API (FAPI), stricter OAuth 2.0 and OpenID Connect profiles that banks and payment services use for open banking APIs.

FIDO2
Users sign in with passkeys or hardware security keys, unlocked by a fingerprint, face or PIN, instead of a password. This resists phishing.

Form SSO
For web apps without SAML, the service fills in each user’s stored ID and password on the login form. This still relies on passwords and breaks when the form changes.

ISMAP
Registered under the Information system Security Management and Assessment Program (ISMAP), the national government’s security assessment for cloud services used by public bodies. Public-sector tenders often require it.

Windows MFA
An agent on each PC adds MFA or passwordless sign-in to the Windows login itself, which web single sign-on does not cover.

Zero Trust
Each sign-on is checked against signals such as a device certificate, endpoint security status, or an unusual time or location, instead of trusting the network.
