🧮 For Accounting Firms

Sign into your clients' Login.gov
without a password and without 2FA.

Access systems like IRS, HMRC, Companies House and Login.gov quickly and smoothly, distributing access to your team in a controlled and monitored way. On top of that, 4Keyless lets your AI agents and RPA reach every tax and payroll portal, while the certificate, the Login.gov password and the 2FA never leave the vault.

🇺🇸 IRS 🇬🇧 HMRC 🏢 Companies House 🔐 Login.gov 👷 SSA / E-Verify 📋 FinCEN BOI

The real blockers aren't the tax rules, it's the login

Government portals were never built for automation. Certificates, MFA prompts and passwords changed by clients are exactly where your robots break and where secrets leak.

Without 4Keyless

  • Login.gov / IRS MFA (SMS or app) stops every unattended run, someone has to approve it by hand
  • Client certificates and API keys are shared across the whole firm, impossible to know who filed what
  • Clients and staff change portal passwords without warning and the bots silently fail on a filing deadline
  • Credentials copied into scripts, spreadsheets and personal laptops, one leak acts on behalf of the client
  • No trail tying an IRS e-File or an HMRC submission to a specific agent, client or operator

With 4Keyless

  • TOTP two-factor codes are generated and injected automatically, no human waiting on an SMS
  • Certificates stay in HashiCorp Vault; the proxy performs mTLS so the agent never sees the key
  • Rotate a client's password once, in one place, every bot keeps working, no code to redeploy
  • Per-agent, per-client access policies, revoke a single bot without touching the certificate
  • Every filing signed and logged: agent ID, system, client, URL, timestamp, client IP

The three things that keep breaking your automations

Every accounting firm running RPA or AI on government portals hits the same three walls. 4Keyless removes all three.

📱

Government MFA

Login.gov, IRS and HMRC MFA codes are the number-one killer of unattended runs.

  • TOTP secrets stored in the vault, never in the bot
  • Codes generated and injected at request time
  • Runs 24/7 with no human tapping "approve"
🔑

Shared certificates

One client certificate passed around the office is a compliance and liability nightmare.

  • X.509 / eIDAS certificates kept encrypted in Vault
  • mTLS handled by the proxy, the key never leaves
  • Grant or revoke per agent, per client, in seconds
🔄

Passwords changed by clients

Clients and staff rotate portal passwords and every bot silently dies.

  • Credentials live in one place, not scattered in scripts
  • Update once, every automation keeps running
  • Secure upload links so the client rotates it themselves

Payroll & employment

  • SSA employer services
  • E-Verify employment eligibility
  • State unemployment insurance portals
  • EU / eIDAS client-certificate portals

Certificate, password or federated login, the full certificate chain is preserved on upload.

How credential injection works

Store the credentials

Add the client certificate .pfx, the portal password and the TOTP secret. 4Keyless validates them and stores everything encrypted in Vault, or send the client a secure upload link.

Define a policy

Bind agent groups to the portals and clients they may reach and the credential group to use. Add an ASK approval step for sensitive filings.

Agent calls the proxy

The agent makes a normal HTTPS request to IRS, HMRC or Companies House through 4Keyless, with no certificate, password or 2FA in its context.

Proxy authenticates & logs

4Keyless completes the mTLS handshake, injects the password and the TOTP code, and records a signed, tamper-evident audit entry.

Designed for the accountant's duty of care

You hold your clients' most sensitive tax and payroll data. 4Keyless keeps certificates and passwords out of agent context, enforces tenant isolation, and produces an Ed25519-signed trail of every access, supporting GDPR, SOC 2 expectations and your professional duty of confidentiality.

4Keyless is a security and access-governance product, not an accounting or law firm. Nothing here is tax or legal advice; how you automate access to government portals should be validated with a qualified professional and against each system's terms of use.

Give your agents the portals, not your keys.
