The following instructions are excerpted from Okta Help Center, URL -

The SMS Authentication factor allows users to authenticate themselves using a one-time passcode (OTP) that is delivered to their phone in an SMS message.

End-user experience

When this factor is activated, users signing in to Okta for the first time see that extra verification is required.

Set up the SMS Authentication factor for the first time

  1. While signing in, the Sign-In Widget displays the Set up multifactor authentication page.
  2. Click Configure factor.
  3. Select the country your phone number is from in the Country dropdown list.
  4. Type your phone number in the Phone number field. Don't include the country code, leave out any dashes, and leave out the leading zero if your country's phone system uses them.
  5. Click Send code. You receive a code in an SMS message.
  6. Type the code in the Enter Code field.
  7. Click Verify.

Sign in with the SMS Authentication factor

  1. Go to your org's sign-on page. Provide your username and any other credentials requested by the Sign-In Widget, such as a password.

  2. Click the down arrow and select SMS Authentication from the Select an authentication factor list.

  3. Okta sends an SMS message, and the Sign-In Widget displays the Enter Code field. If you don't receive the code automatically, click Send Code.

  4. Type the code provided in the SMS message in the Enter Code field.

  5. Click Verify.

If you changed your phone number and haven't updated it in Okta yet, voice calls and SMS messages go to your old phone number and you can't complete verification. If this happens, click Sign in with something else on the Sign-In Widget, and verify with a different factor. Next, complete the Change the phone number for the SMS Authentication factor procedure, and replace your old phone number with your new one.

Change the phone number for the SMS Authentication factor

Users can change the phone number to which OTP codes are sent by removing the SMS Authentication factor and then setting it up again.

  1. In the Okta Dashboard, click your username in the upper-right corner.
  2. Select Settings.
  3. In the Extra Verification section, click Remove beside SMS Authentication, and click Yes to confirm.
  4. Click Set up beside SMS Authentication.
  5. Continue with the steps in Set up the SMS Authentication factor for the first time (shown above).
