I didn’t receive an email with my code

Try these steps:

• Confirm that you selected the email option.
• Check that you are looking at the email account associated with your My Account profile.
• Check your spam or junk folder. MFA emails are sent from [email protected].
• Wait for the message before requesting another code.
• If you requested more than one code, use only the most recent one.

If the email address associated with your profile is no longer correct, follow the instructions on this page to update it after you regain access.

If none of the above helps, please contact us at 1-800-ALLIANT (800-255-4268).

I didn’t receive a text message with my code

Try these steps:

• Confirm that the mobile number in your My Account profile is correct.
• Check your phone’s blocked-number list.
• Make sure messages from 255255 are not blocked.
• Check your Messages app’s spam or blocked-message folder.
• Confirm that your phone can receive SMS text messages.
• Confirm that your phone has a cellular signal, not only a Wi-Fi connection.
• Try receiving the code by email instead.

Text-message MFA codes are sent from 255255. The exact location of blocked or spam messages varies by phone, messaging app and software version.

If none of the above helps, please contact us at 1-800-ALLIANT (800-255-4268).

A verification code expires five minutes after it is requested. A code also becomes invalid when you request another code.

If you see an expired-code message:

• Select "Resend authentication code."
• Wait for the new code to arrive.
• Enter the most recent code manually.
• Avoid using an older code that arrived after you requested a replacement.
• If AutoFill or copy and paste does not work, type the code manually.

If the problem continues:

• Close and reopen the Alliant Energy mobile app.
• Confirm that you have the current version of the app.
• If you are using a browser, clear its cache and cookies.
• Confirm that your browser is up to date.

If none of the above helps, contact us at 1-800-ALLIANT (800-255-4268).

The text-message option appears only when a mobile number has been added to your MFA settings.

1. Sign in to My Account.
2. Select My Profile.
3. Select User Profile Information.
4. Find the multi-factor authentication section.
5. Select the pencil icon next to the mobile number.
