iPrescribe: What Is Two-Factor Authentication?

Two-factor authentication (2FA) is an extra layer of security used to ensure that people trying to access an online account are who they say they are. The two factors required to authenticate your account are:

  1. Login credentials
  2. Unique Identifier (one-time code)

How Does Two-Factor Authentication Work?

1. You are prompted to sign in with their login credentials (usually, username and password).

2. You are then prompted to initiate a second login step.

  • The user provides a unique identifier to prove their identities, such as a security token or a temporary (one-time pin) six-digit code.

3. Enter the one-time pin (OTP) generated from the previous step.

4. You will receive access to the application or website after entering two-factor authentication. 

  • Providing both factors will authenticate the user and grant access.

Why do I have to authenticate using two-factor authentication (2FA) when I am prescribing a controlled substance?

This is mandated by the DEA and required for controlled substances
