How do I use the Call Me feature for the LastPass Authenticator?

If your account is set up to use the LastPass Authenticator when you access your LastPass Vault and/or sign in to SSO (Cloud) apps, then you can use the "Call Me" feature to use a voice call as an alternate method of authentication.

Note: The Call Me feature is only available when using the LastPass Authenticator as a multifactor option for your LastPass account.
Before you begin: To set up the Call Me feature, you must first follow all of the steps in the Use the LastPass Authenticator article.
Attention: The phone number you set in your Vault's Account Settings is not the phone number used for the Call Me feature. The Call Me feature uses the phone number you set as a backup method for sending security codes when setting up the LastPass Authenticator as your multifactor authentication option for your Vault.
To receive a voice call from LastPass to authenticate via the LastPass Authenticator, do the following:
  1. Log in to LastPass by doing either of the following:
    • In your web browser toolbar, click the inactive (grey or black) LastPass icon inactive LastPass icon, then enter your email address and Master Password and click Log In.
    • Go to https://lastpass.com/?ac=1 and enter your email address and Master Password, then click Log In.
  2. When prompted to authenticate, click Call me.
  3. A phone call is placed from LastPass to the phone number set up for your account (which you enrolled when you set up the LastPass Authenticator as your multifactor option).

    Result: When you answer the call, the automated voice states the following: "Thank you for using LastPass Authentication System. Please press the # sign key to finish your verification."

  4. When prompted, press the # key on your phone's keypad.

    Result: The automated voice states, "Your sign-in was successfully verified. Goodbye" and the call ends.

    Troubleshooting: If the automated voice states, "Your sign-in was declined. Goodbye" and the call ends, it means that you did not press the # key on your phone's keypad in time to verify. Please sign in again with your email address and Master Password to be prompted for authentication again.
