Enable Multi-Factor Authentication (MFA) for All Transactions – Proof Help Center
Proof account owners and admins can enable multi-factor authentication (MFA) for all transactions by requiring signers to verify their identity via SMS or voice call (voice call available on Premium tiers) before completing transactions, with options to adjust MFA per transaction, and manage settings through the Transaction settings page, while troubleshooting includes editing signer phone numbers and contacting support if codes are not received.
Audience: Organizations
Owners and admins can require signers to verify their identity via SMS or voice call before completing any transaction sent from your organization account.
Notary-Sourced Transaction Notaries (NSTs) are not able to use this feature.
How It Works
After transaction MFA is enabled:
- Signers on all future transactions will be required to use multi-factor authentication before completing their transaction.
- You can change MFA for a single transaction if needed.
Depending on your settings and the transaction type, signers may have different options to receive their authentication code:
- Notarize transactions: SMS text message
- Sign transactions: SMS text message or voice call*
*Voice call authentication is available on Premium or higher tiers only.
Enable Transaction MFA for All Transactions
- 1.Log in to your Proof account.
- 2.Click Settings from the navigation panel on the left.
- 3.Select Transaction settings from the Settings page menu.
- 4.Select the radio button next to the desired authentication method in the Authentication & security box.*
- Business and real estate accounts can use SMS authentication.
- Title accounts also have the option to use ZIP code.
- 5.Click Save changes.
Troubleshooting
- If the signer's phone number is entered incorrectly, an owner or admin can edit the transaction so the signer can try again.
- If the signer is still not receiving their code and the number is correct, contact Proof support.
After 3 failed attempts to enter the correct authentication code, the user will be locked out for 10 minutes.
Summary Checklist
- Go to Settings → Transaction settings
- Select your preferred authentication method under Authentication & security
- Click Save changes
If you need further assistance, you can submit a support request or chat with the support team from any page in the app.

Multi-Factor Authentication (MFA) Overview
Proof employs multi-factor authentication (MFA) to enhance security by requiring users to provide two or more verification factors—knowledge, possession, or inherence—where login MFA, mandatory for all notary accounts, protects account access via codes sent by text or authenticator apps, while transaction MFA, available only to organizations, verifies recipient identity through phone authentication with premium tiers allowing voice call options for sign-only transactions.
The Evolving Landscape of Authentication | Proof
The blog explores five advanced authentication methods, focusing on app-based and continuous authentication, explaining how app-based authentication uses time-sensitive codes generated on a device to prevent phishing and SIM-swapping, while continuous authentication monitors user behavior throughout a session to ensure ongoing identity verification, with Proof enhancing security by integrating these methods into a comprehensive identity assurance framework combining device, document, and biometric verification.
Multi-Signal Fraud Detection Benchmarks
Proof has developed a layered fraud detection model that combines passive signals, active checks, and collective telemetry from its Identity Authorization Network to outperform traditional passive-only methods by 600-1,300% in detecting sophisticated fraud without increasing user friction, addressing the shortcomings of standard approaches like MFA and KBA that are increasingly ineffective against targeted attacks.
Introducing Persistent Identity: The Foundation of Repeatable Trust
Persistent Identity is a secure digital ID system that enables individuals to verify their identity once to a high-assurance standard, store it on the Proof platform, and reuse it across multiple online transactions and organizations via the Identity Authorization Network, thereby reducing inefficiency, abandonment rates, and trust erosion caused by repeated identity verifications in an increasingly digital and threat-prone environment.
Enable Login Multi-Factor Authentication (MFA) for Your Organization – Proof Help Center
The Proof Help Center article explains how organization owners and admins can enable mandatory login multi-factor authentication (MFA) via SMS or authenticator app for all team members—including all notary accounts and Pro/Premium tiers—by toggling the MFA setting in Team Security, which overrides individual user settings and prompts users to authenticate with a 6-digit code at next login.
23 NYCRR Part 500 Is a Regulatory Shift from Authentication to Attribution
The updated 23 NYCRR Part 500 regulation by NYDFS, completed in November 2025, mandates stronger multi-factor authentication and governance for financial institutions, signaling a shift from traditional authentication methods based on secrets to a more robust architectural approach that addresses the industrialized and sophisticated nature of modern credential theft and systemic cyber risk.
