If you have received an email notifying a successful new login from SMART VALOR and this wasn't you, it means somebody has gained access to your login credentials and has signed in using them.
If your account was properly set up, you should already have 2FA enabled. In such case, if only the password would be compromised, it would be impossible for the person to gain access to your dashboard. However, if both factors (password and 2FA authentication codes) are compromised, then there is a risk of misuse of your account.
In any case, to ensure that your account is not further compromised and misused, immediately change your account password to a new and unique one, and update your 2FA settings.
Check also if you received any additional emails with regards to further activities on your account.
In case of any doubt, shortly contact SMART VALOR support for any relevant information regarding the suspected login.
