Log on to your MFA Account with Yubico Authenticator

Once you have configured your account with a service for authenticator app two-factor authentication, you must use a code generated by Yubico Authenticator when logging in to that service.

Logging on to Your Account, Service, or Website

After you have configured your account for two-factor authentication using the Yubico Authenticator, when logging in to that service you must use a code generated by the Yubico Authenticator.

Step 1:

Launch Yubico Authenticator on your mobile device or computer.
Step 2:

Log into your account or service website on the device (mobile or desktop). Enter your usual credentials: user name and password.

  • You are then prompted for an authenticator code.
Step 3:

Locate the authenticator code from your Yubico Authenticator.

  • Desktop: Insert your YubiKey into your mobile device. The code is listed next to the service’s identification, for example: Issuer (the name of the service). Double-click the authenticator code to copy it.

  • Mobile iOS Lightning port:

    1. Insert your YubiKey 5Ci into your device’s Lightning port.

    2. If the credential requires a touch verification, touch your YubiKey’s sensor. For example with a YubiKey 5Ci. (See Note)

      The code is listed next to the service’s identification, for example: Issuer (the name of the service).

  • Mobile iOS NFC:

    1. Place the Yubikey over the NFC area (pull down) to activate NFC.

    2. When prompted, scan your key.

    3. If the credential requires a touch verification, scan your YubiKey NFC again. (See Note)

      The code is listed next to the service’s identification, for example: Issuer (the name of the service).

  • Mobile Android: Tap and hold your NFC-enabled YubiKey against the NFC antenna on the back of your phone. The code is shown next to the service’s identification, for example: Issuer (the name of the service).

  • Note: For generating codes set to require touch, tap the refresh icon next to the credential, then scan the YubiKey a second time when prompted. Touch credentials work this way over NFC because NFC does not provide enough power for the capacitive touch sensor on the YubiKey to function.
Step 4:

Paste (desktop) or Enter (mobile) the code into the appropriate field on the service website or account and click Sign In (or similar).

TIP: In Yubico Authenticator for Desktop, you can double-click the code, and then paste it into the field for the authenticator code.
