Ameren's New Log In & Registration Process

Are you getting an error message when logging in? Try this:

  1. Confirm that you are using an email address. Your previous UserID will not work. See the FAQ below for details.
  2. Reset your password by clicking "Forgot Password" using the same email address you tried to log in with.
  3. Use your email address to create a new online profile at Ameren.com. You will gain access to new account management features.
  4. Still having issues? Contact us. We'll help you out.

Why did Ameren update the log in experience? In our continued efforts to improve our customer experience, we simplified the Ameren.com log in process to allow your email address to serve as your UserID. You'll also find easier online account management and improved security through multi-factor authentication.

What if I enter the wrong information during setup? You can make additional updates to your information from the My Profile section, including the ability to change your UserID (email address).

Will my UserID change if I updated my email address? Yes. If you update your email address in the "My Profile" area, your UserID will be updated to that email address.

What is multi-factor authentication? This is an additional security measure to confirm the person entering the information is who they say they are. This replaces the security questions you were previously asked.

I have a residential and a commercial account. Do I need to create an account for each type? No. Your new UserID is designed to support multiple roles. If you have a personal residential account but also manage a commercial account, you can now use the same UserID to manage both.

I use one of the special portals for business partners. How will sign in work for me? Instead of signing up as a CBP, you'll click "I am a utility partner" and follow the prompts. All the portals will still function just as they did before.

I also use the Ameren Mobile App. Will my UserID and password change there, too? Once you create a new online account at Ameren.com, you'll use those same login credentials on the new Mobile App.

I've read all the FAQs and I'm still stuck. What do I do? Contact us. We'll help you out.
