What is multi-factor authentication?

Multi-factor authentication (also known as MFA) is a security measure that requires customers to enter a code sent via text message or via email as an additional identity factor before accessing their account.

Why is multi-factor authentication required?

Your protection is our priority, we have upgraded your login experience to increase customer account security with the introduction of multi-factor authentication or MFA.

How does Synergy’s multi-factor authentication for My Account work?

To log in to My Account, you will need to authenticate your account access using the mobile number or email address linked to your Synergy account. You will also need to enter your supply address exactly as it appears on your Synergy bill. 

The validation will send a one-time use code to the mobile number or email address that is linked to the Synergy account, which you will need to enter correctly before you can log on. You will only have 3 attempts of the mobile number and supply address authentication  , so please ensure you have entered these details correctly. 

The SMS or email code should be sent instantly, so ensure that you check your junk emails or spam SMS folders if it hasn’t come through within one minute of requesting it. The SMS or email code expires after five minutes and you will need to request a new code after that time. 

If this happens, you can click on the “I didn’t get a code” link, which can be requested up to 3 times per day. The number of remaining code generation attempts will show on the error message.

If you fail to authenticate your account after three attempts, My Account will be locked and you will need to contact us on 13 13 53 between Monday to Friday 7am to 7pm (residential customers), or on 13 13 54 between Monday to Friday 8am to 5pm (business customers) to check your details and to reset My Account.

How do I add a mobile number or email address to my Synergy account?

Please call our contact centre on 13 13 53 between Monday to Friday 7am to 7pm (residential customers), or on 13 13 54 Monday to Friday 8am to 5pm (business customers), to update your account details.
