Verify the person during onboarding, enroll the verified person in your company identity system, then authenticate each access session and grant only role-appropriate permissions. These are separate checks: a password, MFA prompt, or security key can help authenticate an enrolled account, but none proves by itself that a new hire is the person they claim to be.
Separate identity proofing, authentication, authorization, and device checks
These controls answer different questions. Treating them as interchangeable can leave a gap—for example, a well-secured account may still have been issued to the wrong person, or a correctly authenticated employee may have excessive access.

| Control | Question it answers | When it matters |
|---|---|---|
| Identity proofing | Is this person the employee they claim to be? | Before creating or binding company credentials to the employee’s identity. |
| Authentication | Is the person using an enrolled account its legitimate subscriber? | When the employee signs in or starts a remote-access session. |
| Authorization | Which systems and resources may this authenticated employee use? | When assigning and evaluating access to company resources. |
| Device posture | Does the endpoint meet the organization’s security conditions? | When deciding whether and how the device may connect. |
Choose assurance based on the access at stake
Start by identifying the systems, data, and privileges the role needs. A person who can reach sensitive systems or make consequential changes may warrant stronger proofing and authentication than someone with limited access. Do not assume that checking one document is sufficient for every role or system.

NIST’s Digital Identity Guidelines provide a framework for making these decisions. The current suite, SP 800-63-4, was published in July 2025 and supersedes SP 800-63-3. Its companion SP 800-63A-4 addresses identity proofing and enrollment and defines three identity assurance levels; SP 800-63B-4 addresses authentication and authenticator management and defines three authenticator assurance levels. Those are separate assurance scales: choose proofing and authentication strength for their respective risks.

NIST writes for government information systems. Private employers can use the publications as technical guidance, but they are not a universal legal requirement or a prescribed hiring-document checklist. Apply your organization’s policy and the laws that govern the places where it operates.
Use a controlled onboarding sequence
-
Set the access and proofing requirements
Define the role’s required systems and privileges, then select a proofing approach proportionate to the consequences of impersonation. Decide who may approve the proofing decision and how exceptions or accessibility needs will be handled.
-
Match the person to trusted hiring records
Compare the applicant’s identity claim with trusted employment and onboarding records, using evidence under the organization’s approved process. NIST SP 800-63A-4 describes proofing as an applicant providing evidence to a credential service provider (CSP) so the CSP can reliably identify them and assert that identity at a useful assurance level. It does not prescribe one universal workflow for employers.

Record the decision and protect the evidence
Document what was checked, who made or approved the decision, and the outcome, according to company policy. Restrict access to proofing material, collect and retain only what is needed, and handle it in line with applicable privacy and retention rules. Requirements vary by jurisdiction.
-
Enroll the verified person and approved authenticators
Only after proofing, associate the employee’s company account and approved authenticators with the verified identity. Set out how the employee can recover an account and replace a lost or compromised authenticator; account recovery is part of the identity lifecycle, not an informal workaround.
-
Require session authentication
Set the authentication strength for the systems and risk involved, using multifactor authentication where appropriate. A hardware security key or other hardware authentication token can be an authentication option after enrollment; it is not proof that the person presenting it is the new hire. For current authenticator requirements, use NIST SP 800-63B-4 rather than treating the older remote-access guide as the current specification.

Verify the remote-access service
Where feasible, configure the employee’s client to check that the remote-access service is legitimate before credentials are sent. NIST SP 800-46 Rev. 1 gives verification of the server’s digital certificate as an example of mutual authentication.

Authorize access and assess the endpoint separately
Grant only the resources required for the employee’s role. Independently check whether the connecting device meets the company’s security baseline; NIST SP 800-46 Rev. 1 describes checks such as patch and anti-malware status, with restricted or quarantine access when a device fails. A compliant endpoint does not prove who is using it.
-
Update or revoke access as circumstances change
Adjust permissions when duties change and revoke access when the employment relationship ends. Maintain authentication and access records under company policy, alongside the proofing and enrollment decision, without retaining sensitive evidence longer than applicable rules and policy permit.
Evaluate proofing and authentication options against practical trade-offs
There is no single evidence method or authenticator that is best for every workforce. Compare options against the needs of the role and the employees who must use them.
- Proofing evidence: consider evidence quality and resistance to impersonation, as well as accessibility, employee friction, privacy and data minimization, geography and legal applicability, and operational cost.
- Authenticators: consider the required assurance and phishing resistance, recovery risk, device compatibility, deployment and replacement effort, and usability.
- Remote-access design: consider resource-level authorization, endpoint-condition enforcement, logging, recovery procedures, and the user experience.
