can someone access my accounts

Yes and no. If you had your passwords written down or saved to a text file, they could've gained access to that information and copied it. If your passwords are only saved in your browser, they're pretty safe. Any connection to sites that have https security enabled (banks, shopping sites, etc.) will transmit login and password from your computer to their site using encryption.

If you have reason to believe that your passwords have been compromised, it's time to change them. In this article, we provide password guidance: https://www.whatismyip.com/personal-internet-security/
