Sign in with Google or Microsoft

No new password to manage. Log in with your existing Google Workspace or Microsoft 365 account — one click and you're in.

📲

Two-factor authentication

Every account is secured with 2FA. Even if credentials are compromised, your fax number and PHI stay protected.

Instant setup

We configure everything on our end. Nothing to install or configure on yours.

HIPAA-compliant faxing

Built for healthcare from the ground up. Every fax you send or receive is protected by the same standards your practice depends on.

🔒
HIPAA Compliant Suitable for transmitting Protected Health Information (PHI)
🔑
SSO + 2FA Sign in with Google or Microsoft · 2FA enforced
🔐

TLS encryption in transit

All email and fax traffic is encrypted using TLS. PHI is never transmitted in plaintext at any point in the delivery chain.

🗑️

Zero data retention

Fax content and PDFs are not stored on our servers after delivery. We process and forward — nothing is logged or archived on our end.

📋

BAA available

We'll sign a Business Associate Agreement with your organization. Required for HIPAA compliance — just ask when you sign up.

🚫

No third-party sharing

Your fax data is never sold, shared, or analyzed. It flows directly from sender to your inbox, with no intermediary access.

🔑

Access controls

Each fax number is bound to a single authorized email address. Only your account can send or receive from your number.

📞

Secure last-mile delivery

Outbound faxes transmit over the PSTN using encrypted endpoints. The receiving fax machine is the only destination.

🔑

Google & Microsoft SSO

Sign in through your organization's Google Workspace or Microsoft 365 identity provider. No standalone passwords stored on our end.

📲

Two-factor authentication

2FA is enforced on all accounts. Access requires both your SSO credentials and a second factor — keeping accounts secure even if a device is lost.

Faxing.io is designed to support HIPAA compliance for covered entities and business associates. BAA available upon request. Customers are responsible for ensuring their own HIPAA obligations are met end-to-end.
