How to use a one-time login code

When multi-factor authentication is enabled, we’ll ask you for a one-time code in addition to your password each time you sign in to confirm your identity.

To log in with your one-time code:

  1. Log into your Fullscript account with your email address and password.
  2. Enter the one-time code that was sent to your phone or email, or generated by your authenticator app.

Note:

Codes usually arrive within a few seconds, but occasional delays can happen. Requesting a new code invalidates the previous one. Entering an old code will cause an error.

To avoid issues, wait a few moments before selecting Resend.

  1. Click Next.
    enter your one-time code and click next

Tip!

If you are unable to access your phone or authenticator app, click Use backup code to sign in.

Log in with a backup code

If you’ve lost access to your multi-factor authentication method, use a backup code to access your account. Backup codes are provided during set up, with prompts to copy and store them securely.

To sign in to your account with a backup code:

  1. Sign in with your email and password.
  2. When asked for your one-time code, click Use backup code to sign in.
    Click Use backup code to sign in.
  3. Type in the backup code you were given when you set up multi-factor authentication.
  4. Click Next.
  5. You’ll be given a new backup code, as the previous one is now expired. Copy and securely store that backup code.
    Copy the new code.
  6. Click Next to complete the login process.

With multi-factor authentication enabled, you’ll need a one-time code or backup code to log in. If you can’t access either, contact our customer support team to recover your account.

How to add a trusted device for login

Once multi-factor authentication is set up, you can mark a device as trusted the next time you sign in. This lets you skip the extra authentication steps on future sign-ins.

To mark a device as trusted, click the Trust this device checkbox when you provide your one-time code. Then click Next to sign in and complete the set up process.

Click Trust this device before you finish signing it.
Click Trust this device before you finish signing it.
